Anal Sac Disease in Cats

The anal sacs are two small pouches located on either side of the anus at approximately the four o'clock and eight o'clock positions. The walls of the sac produce a foul smelling fluid which is released whenever the cat passes a bowel movement. The anal sacs or their ducts can become inflamed or infected due to a variety of causes. Most cats will respond well to pain relief medications and antibiotics (for several days until the swelling and inflammation have subsided. If a cat has several episodes of anal sac disease, and diet or supplements do not relieve the problem, the anal sacs can be removed surgically.

Anesthesia for Cats

Anesthesia is accomplished by administering drugs that depress nerve function. It is important that you fully understand what will happen to your pet, and that you acknowledge that you understand the risks. Anesthetic monitoring in a veterinary hospital is similar to that found in any human hospital. With today's anesthetics, many of which are reversible, your pet should be almost completely normal by the time of discharge.

Bladder Stones in Cats

Bladder stones are rock-like formations of minerals that develop in the urinary bladder. All stones form because of disease or inflammation in the bladder. The most common signs of bladder stones in the cat are blood in the urine and straining to urinate. Large stones may act almost like a valve, causing an "on-off" or partial obstruction at the neck of the bladder. In males, small stones become lodged in the urethra and cause an obstruction. X-rays (with or without contrast dyes) or ultrasound may be necessary for diagnosis. The fastest way to remove bladder stones is via a surgical procedure called a cystotomy. Special diets or passing a catheter may be successful for some bladder stones. Your veterinarian will advise you of the best course of action for your cat’s particular situation.

Cruciate Ligament Rupture in Cats

The word cruciate means 'to cross over' or 'form a cross'. The cruciate ligaments are two bands of fibrous tissue located in each knee joint. They connect the femur and tibia (the bones above and below the knee joint). The knee joint of the cat is one of the weakest in its body. When severe twisting of the knee joint occurs; the anterior or cranial cruciate ligament most commonly tears or breaks.

Diaphragmatic Hernia in Cats

The diaphragm is the muscular partition that separates the abdomen and the chest. Tearing or disruption of this thin muscle is called a diaphragmatic hernia or diaphragmatic rupture. The most common cause of diaphragmatic hernia is blunt force trauma. Clinical signs are dependent on the severity of herniation. There is often respiratory distress, an abnormal heart rhythm, muffled heart and lung sounds, and other signs of systemic shock. The abdomen may feel empty when palpated. Once the patient is stable, the hernia must be corrected surgically.

Fight Wound Infections in Cats

Wounds in cats often go undetected, but can cause significant problems the longer they are present. Wounds can be easily prevented by keeping your cat indoors, but if they occur, treatment by your veterinarian is recommended. Certain viral infections can cause wounds to persist and can be transmitted through biting.

Hematoma of the Ear in Cats

Ear hematomas are a collection of blood, either fresh or clotted, within the pinna. Excessive or violent shaking causes one or more blood vessels to break, resulting in bleeding into the space between the ear cartilage and skin on the inner surface of the ear. There is often an underlying cause which must be treated but additionally, surgery or drainage should be done to help relieve discomfort. Failure to treat will lead to a misshapen ear caused by damage from inflammation.

Ingestion of Foreign Bodies in Cats

Cats are curious by nature. They love to investigate new sights, smells, and tastes. Unfortunately, this curiosity can lead them into trouble. Cats are notorious for ingesting thread, wool, paper, rubber bands, plant materials, and small toys. Not all foreign objects pass through the digestive tract without complication.

Joint Subluxations in Cats

A joint luxation is a dislocation or complete separation between the bones that normally articulate to form a joint. Subluxation is the term referring to a partial separation of the joint. The most commonly subluxated joint in cats is the hip, although any joint can be affected. Your veterinarian may be suspicious of a joint subluxation based on a history of trauma and physical examination findings such as pain and limping. A radiograph is necessary to definitively diagnose a joint subluxation. In many cases, the joint can be reduced or replaced to its original orientation by a procedure called a closed reduction with prognosis being good if treated immediately.

Laser Surgery for Cats

Laser surgery is a procedure that generates a beam of light energy at a specific wavelength, resulting in the cutting of tissues. There are three major advantages of laser surgery when compared to traditional stainless steel surgical scalpels, which are decreased pain, decreased inflammation, and improved tissue healing. Routine procedures such as ovariohysterectomy and castration are commonly done with laser.

Megacolon in Cats

If the nerves to the colon do not function normally, the muscles of the colonic wall will not contract properly. The muscles then become stretched and the colon enlarges in diameter. Rather than being pushed into the rectum in a normal manner, fecal material accumulates in the distended colon, resulting in severe constipation called obstipation. This massive enlargement of the colon and the resulting constipation is called megacolon. Megacolon is often treatable using a medical approach but some cases require surgical intervention called subtotal colectomy.

Nasopharyngeal Polyps in Cats

Nasopharyngeal polyps are benign idiopathic masses originating from the middle ear that extend either down the eustachian tube or into the external ear. They can cause stertor, nasal discharge, otitis, otic discharge and head tilt. Diagnosis may involve visualization through otoscopic exam or behind the soft palate, but usually needs radiographic evidence or more advanced imaging such as CT or MRI. Treatment involves debulking the mass through traction which has a high rate of recurrence, or more advanced surgery into the bulla to remove the source of the polyp.

Post-Operative Instructions in Cats

After arriving at home, you should keep your cat warm and comfortable by providing a soft clean bed, ideally in a quiet and draft-free room at a comfortable room temperature. Your cat should remain indoors. For most procedures, your cat's activity should be restricted for one full week after surgery. Some cats experience nausea after general anesthesia, so dividing meals into smaller portions may decrease the risk of nausea and vomiting.

Pyometra in Cats

Pyometra is defined as an infection in the uterus. Pyometra is considered a serious and life threatening condition that must be treated quickly and aggressively. Pyometra may occur in any sexually intact young to middle-aged cat; however, it is most common in older cats. Typically, the cat has been in heat within the previous 4 weeks.

Surgical Pins and Plates in Cats

The main objectives of fracture repair are to promote rapid healing of the fracture and to get the cat using its leg as quickly as possible. In most cases, this involves rebuilding the broken bone and fixing it in that position with metallic implants. Post-operative care includes pain medications, antibiotics, adequate nutrition, exercise restriction, and physiotherapy. Most fractures can be repaired very effectively and in many cases, your cat will resume normal activity.

Umbilical Hernia in Cats

An umbilical hernia is a protrusion of the abdominal lining, abdominal fat, or a portion of abdominal organ(s) through the area around the umbilicus. An umbilical hernia can vary in size from less than a ¼” (1cm) to more than 1” (2.5cm) in diameter. Small (less than ¼” or 1cm) hernias may close spontaneously (without treatment) by age 3 to 4 months. If the hernia has not closed by the time of spaying or neutering, surgical repair of the hernia is recommended and prognosis is excellent.

Anal Sac Disease in Dogs

The anal sacs are two small pouches located on either side of the anus at approximately the four o'clock and eight o'clock positions. The walls of the sac produce a foul smelling fluid which is released whenever the dog passes a bowel movement. Bacteria that are normally present in the feces can readily travel up the ducts and enter the sacs resulting in infection. The first sign is often scooting or dragging the rear along the ground. Treatment for impaction involves expressing or emptying the sacs. Antibiotics are often prescribed. Most dogs will require pain relief medications for several days until the swelling and inflammation have subsided. In recurrent or severe cases, surgical removal of the sacs may be necessary.

Bladder Stones in Dogs

Bladder stones are rock-like formations of minerals that develop in the urinary bladder. The most common signs that a dog has bladder stones are hematuria and dysuria. Bladder stones can develop within a few weeks or they may take months to form. Most bladder stones are visible on radiographs or an ultrasonic bladder examination. There are three main treatment options for bladder stones: 1) surgical removal; 2) non-surgical removal by urohydropropulsion, or 3) dietary dissolution. Prevention is possible in some cases, depending on the chemical composition of the stones.

Bloat: Gastric Dilatation and Volvulus in Dogs

Gastric Dilatation and Volvulus (GDV) is an acute life-threatening condition where the stomach fills with large amounts of air and then twists around effectively cutting off the outputs to the esophagus and intestine. It then continues to expand putting pressure on the mucosa, major vessels and diaphragm. Because of the constriction of major vessels returning to the heart the dog will collapse from lack of oxygen and nutrients to vital organs. Underlying causes are still a mystery but most dogs affected are large breed, deep chested male dogs although any dog can experience GDV. There is a definite risk in dogs that have eaten large meals and then exercise. Bloat may be diagnosed by physical exam but radiographs and other testing is needed to show volvulus. Treatment involves decompressing the stomach with a stomach tube or a percutaneous catheter, shock treatment with IV fluids and emergency medications, surgery to correct the volvulus and identify and remove any necrotic areas of stomach or spleen. Mortality rate ranges from 15-40% in treated cases. There is no guaranteed prevention for GDV but gastropexy can reduce the risk. Attention to diet, feeding and exercise may also prevent gastric dilation.

Bone Diseases of Growing Dogs

There are many causes of limping and lameness in young dogs. Most of these are relatively minor and resolve without medical or surgical intervention. However, there are other causes that are more serious and, if not treated promptly, may result in permanent lameness or lead to debilitating arthritis.

Cervical Stenosis (Wobbler Syndrome) in Dogs

Cervical stenosis is caused by compression of the spinal cord, usually at the base of the neck. Although the spinal cord compression occurs in the neck, the hind legs are often affected first. In severe cases, the dog may suddenly develop total paralysis of all four limbs. The condition is most prevalent in Great Danes and Doberman Pinschers. It is diagnosed by myelography, CT scans, or MRI. Anti-inflammatory drugs and analgesics may relieve the initial discomfort, but the greatest chance of success lies with surgery. Most pets enjoy a relatively normal lifestyle following surgery.

Caesarean Sections in Dogs - Post-Operative Instructions

A caesarean section is a major surgery usually performed in an emergency to help deliver puppies. As with any anesthesia, the dog may be sleepy but should be able to eat a high quality diet and nurse puppies within a few hours. The dog should be monitored for fever, abnormal vulvar discharge, and abnormalities at her incision. It is important to ensure that puppies are able to nurse well. If not, or if the dog can not produce enough milk, then commercial milk replacer is recommended. Colostrum ingestion is important for immune protection. If puppies are not nursing within the first 24 hours, then they will need additional veterinary care. Ambient temperature is important in the first 2-4 weeks after birth as puppies cannot regulate their temperature well.

Cruciate Ligament Rupture in Dogs

The cruciate ligaments are two bands of fibrous tissue located within each stifle joint. They join the femur and tibia together so that the knee works as a stable, hinged joint. The two most common causes of cranial cruciate rupture are trauma and degeneration of the ligaments within the joint. During the lameness examination, your veterinarian will try to demonstrate a particular movement, called a cranial or anterior drawer sign. There are various surgical techniques performed to stabilize the knee joint following cruciate rupture. Regardless of the technique used to stabilize the joint, arthritis is likely to develop in the joint as your dog ages.

Retained Testicle (Cryptorchidism) in Dogs

Cryptorchidism (retained testicles) is a fairly uncommon disease that can be passed on to future litters. Clinical signs are uncommon unless complications develop. Testicular cancer and spermatic cord torsion are two complications that can occur with cryptorchidism. Neutering easily corrects the problem.

Ununited Anconeal Process (UAP) in Dogs

The anconeal process is a small projection of bone on the ulna, the longer of the two bones of the forearm. If the anconeal process does not fuse to the rest of the ulna correctly during growth, it causes a condition called ununited anconeal process (UAP). This problem appears to be hereditary mostly in large breeds. When this part of the ulna does not fuse, the elbow joint becomes unstable, causing lameness and pain. Treatment requires surgery. Some form of rehabilitation will improve your dog's chances of making a full recovery from surgery and minimize lameness problems.

Learn More

Degenerative Disc Disease in Dogs

The spinal cord is one of the most important and sensitive organ systems in the body. If it is damaged, the nerve cells do not regenerate but are replaced with fibrous or scar tissue. To protect it from damage, the spinal cord runs through a bony canal within the spine and is surrounded by protective bone everywhere except the junction of the vertebrae. These junctions are filled by rubber-like cushions called intervertebral discs. Degenerative disc disease causes spontaneous degeneration of the outer part of the disc, resulting in sudden disc rupture or herniation.

Keratoconjunctivitis Sicca (KCS) or Dry Eye in Dogs

Keratoconjunctivitis sicca (KCS) is a condition that is also commonly referred to as dry eye. It is a common eye condition resulting from inadequate production of the aqueous portion of the tear film by the lacrimal gland or the third eyelid gland. Any condition that impairs the ability to produce adequate amounts of tear film can result in dry eye. Most dogs with KCS have painful, red, and irritated eyes leading to squinting. The treatment of dry eye is to stimulate tear production and to replace tear film. The prognosis for dogs diagnosed with KCS has never been better.

Lameness in Dogs

Lameness refers to an inability to properly use one or more limbs. It is most often associated with pain or injury. The most common causes of acute or sudden lameness in dogs are soft tissue injury (strain or sprain), injury to a joint, bone fracture, or dislocation. Osteoarthritis and hip dysplasia may also cause lameness in dog. Your veterinarian will determine the best course of action based on your pet's condition and the results of diagnostic tests. Lameness of unknown origin is common in dogs of all types and sizes. In some cases, a trial with anti-inflammatory medications may be necessary.

Laryngeal Paralysis in Dogs

Laryngeal paralysis is a condition that causes dysfunction of the larynx causing reduced ability to breathe deeply and can obstruct the airway. It can be a congenital condition of young dogs or may be due to a neuromuscular disease in older dogs. Clinical signs include coughing, noisy breathing, exercise intolerance, and there may be a change in the sound of the bark. Definitive diagnosis is made thorough examination of the larynx with an endoscope or laryngoscope under sedation. Treatment of mild cases involves environmental management to reduce any stress to the larynx with medications used for flareups. More severe or congenital cases require surgery.

Lens Luxation in Dogs

The lens is the transparent structure within the eye that focuses light on the retina. The lens can fall backwards into the eye known as a posterior luxation, where it rarely causes discomfort, or it can fall forwards into the eye, called an anterior luxation. Anterior luxation blocks the drainage of fluid from the eye resulting in glaucoma or increased intra-ocular pressure (IOP). An anterior (forward) luxation is an emergency and can lead to further complications such as glaucoma and blindness. Surgery can help preserve vision if done promptly, but ultimately some cases may lead to removal of the entire eye. If the lens luxates posteriorly, or falls into the back of the eye, it causes little or no discomfort. These cases may not require any treatment.

Lumbosacral Syndrome in Dogs

Cauda equina syndrome or lumbosacral syndrome is a condition caused by the narrowing of the spinal canal and results in compression of the spinal nerve roots; pressure on the nerves that exit the spine cause the clinical signs. This pressure may be due to a narrowed spinal canal caused by arthritis, intervertebral disc herniation, an infection in the disc, trauma, congenital malformation, or a spinal tumor. Dogs with lumbosacral syndrome are in pain. If the clinical signs and radiographs are suggestive of cauda equina syndrome, a myelogram, is performed. Treatment of cauda equina involves either conservative medical treatment or surgical intervention. This is dependent upon the duration and severity of the signs, as well as the owner's finances.

Luxating Patella in Dogs

The patella, or kneecap, is normally located in a groove on the end of the femur (thigh bone) just above the stifle (knee). The term luxating means out of place or dislocated. Therefore, a luxating patella is a kneecap that moves out of its normal location. Pet owners may notice a skip in their dog's step or see their dog run on three legs. Then suddenly they will be back on all four legs as if nothing happened. Many toy or small breed dogs, including Maltese, Chihuahua, French Poodles, and Bichon Frise dogs, have a genetic predisposition for a luxating patella. Surgery should be performed if your dog has recurrent or persistent lameness or if other knee injuries occur secondary to the luxating patella.

Legg-Calve-Perthes Disease

The femoral head is the ball part of the hip joint and if it develops necrosis or dies, it can no longer function properly. Necrosis is due to loss of the blood supply to the femoral head, which may be the result of a growth abnormality or trauma to the hip. It is a hereditary condition of small breed dogs. The most common clinical signs are slowly progressing hind limb lameness, with resulting inability to bear weight on the affected limb or both hind limbs. Diagnosis is made by radiographs of the hip joint. The treatment of choice is femoral head and neck ostectomy which results in a good prognosis.

Portosystemic Shunt in Dogs

A portosystemic shunt causes a bypass of blood from the gastrointestinal tract directly into the systemic circulation, avoiding the normal detoxifying process that happens in the liver and reducing nutrient input into the liver. Liver shunts can be congenital defects (failure of closure of the ductus venosus or inappropriate vascular development) or acquired (development of extra vessels caused by portal vein hypertension). Clinical signs include failure to thrive (runt), head pressing or other neurological signs especially after high protein meals, delay in anesthetic recovery, increased urination, and vomiting or diarrhea. CBC and biochemistry can be altered in a dog with a portosystemic shunt (e.g., microcytic anemia, low BUN, glucose, elevated ALT) and urinalysis can show abnormal crystals and possibly infection. Bile acids will be elevated. CT, ultrasound, or other more advanced imaging will confirm and locate the shunt. Initial treatment includes a change to a low protein diet, lactulose to absorb ammonia and other toxins, and antibiotics to change the bacterial population of the intestines. Some dogs do well with medical management; however, many need surgical treatment to gradually close off the shunt. Surgery is very successful and dogs return to normal in 2-4 months.

Pyometra in Dogs

Pyometra is defined as an infection in the uterus. Pyometra is considered a serious and life threatening condition that must be treated quickly and aggressively. The preferred treatment is to surgically remove the infected uterus and ovaries. Another approach to treating pyometra is the administration of prostaglandins, although the success rate is highly variable.

Surgical Discharge Instructions for Dogs

The post-operative period is just as important as the surgery itself. Following the set instructions will help avoid complications and lead to a smoother recovery. Monitor the incision daily for signs of redness, swelling, discharge, or excessive licking. Consider using an Elizabethan collar to keep your dog from licking the incision site. Should you have any concerns, contact your veterinarian immediately.

Tumors in Ferrets

Malignant lymphoma (lymphosarcoma) and leukemia are among the most common malignancies seen in ferrets. Diagnosis may be made by fine needle aspiration or biopsy. For a dedicated owner with a compliant patient, surgery and/or treatment with chemotherapy is an option. Remission of lymphoma is possible with treatment in ferrets, but recurrence is common. Ferrets also commonly develop insulin-producing tumors of the pancreas that lower the ferret’s blood sugar and cause weakness, weight loss, lethargy, seizures, coma, and death. Insulinoma commonly spreads from the pancreas to the liver, so surgical removal of pancreatic insulinoma nodules may not be curative. Affected ferrets respond well for months to years to medical therapy with glucose-promoting drugs (prednisone) and anti-insulin drugs (diazoxide). Drugs suppress effects of the tumor but do not eliminate it; and ferrets on medical treatment must have their medications increased over time as the tumor grows.

Ectopic Cilia or Eyelash Problems in Dogs

Ectopic cilia can be an irritating eye problem for many dogs. Growing abnormally through the conjunctiva, they come into contact with the cornea and can cause chronic discomfort to the eye and corneal ulceration. Surgery is necessary to help to correct the problem in order to help dogs live a more comfortable life. The prognosis for surgical correction of this condition is generally good.

Eyelid Ectropion in Dogs

Ectropion, or outward rolling of the eyelid, can cause problems such as recurring conjunctivitis and drying out of the cornea. The clinical signs are a 'sagging' or 'rolling outward' lower eyelid. A thick mucoid discharge often accumulates along the eyelid margin. Diagnosis is usually made on physical examination. Acquired ectropion can occur in any dog at any age. Testing for hypothyroidism and for antibodies against certain muscle fibers may be done if looking for underlying causes. The treatment for mild ectropion generally consists of medical therapy; if the condition is severe, surgical correction can be performed to shorten the eyelids.

Eyelid Entropion in Dogs

Entropion, or rolling in of the eyelids, is seen in many breeds and is considered a hereditary disorder. Most dogs will squint, hold the eye shut, and tear excessively (epiphora) though some patients will develop a mucoid discharge. Entropion can cause additional eye problems, such as corneal ulcers, perforations, or development of pigment on the cornea interfering with vision and can be chronically irritating to the dog. Entropion is corrected with surgery.

Fragmented Coronoid Process (FCP) in Dogs

FCP is a developmental defect of one of the coronoid processes. A genetic component is thought to be involved and males appear to be more commonly affected. It is usually seen in large breed dogs such as Bernese Mountain Dogs, Golden Retrievers, Labrador Retrievers, Rottweilers, and German Shepherds. Lameness usually develops in the foreleg of young dogs. Several radiographs of each affected leg, with the leg in different positions, are necessary in order to get an accurate assessment of various bones and joints. Surgery is the treatment of choice for this condition, and its aim is to remove any abnormal cartilage or bone in an attempt to return the joint to a more normal anatomy and function.

Health Problems in Rabbits

Rabbits have unique gastrointestinal tracts and need a high-fiber, low-carbohydrate diet to help keep the normal GI bacteria fermenting their food. When they are fed a diet high in carbohydrate, administered certain types of antibiotics, or undergo a rapid diet change, they can develop life-threatening GI stasis. Rabbits with GI stasis become lethargic, dehydrated, weak, lose weight, and must be treated by a veterinarian as soon as possible. Only rarely do rabbits develop true GI tract obstructions from ingesting foreign objects and require surgery to remove the obstruction. Rabbits are coprophagic, consuming cecotropes overnight that serve as a source of critical protein and vitamins. Rabbits that eat high calcium alfalfa-based diets or high-calcium vegetables are prone to developing bladder stones that must be removed surgically. Bunnies housed at temperatures over 80°F are subject to heat stroke, since they cannot sweat and should be housed inside in a cool place, or if outside, should have plenty of shade and water.

Diseases in Rodents

Common conditions of pet rodents include respiratory diseases, gastrointestinal problems, dental problems, and tumors. Signs of respiratory disease in rodents include nasal and/or ocular discharge in mild infections, and wheezing, coughing, and open-mouth breathing in severe infections. Gastrointestinal disease, including diarrhea from various causes and gastrointestinal stasis is common in pet rodents. All rodents have teeth that grow continuously throughout their lives. Occasionally, these teeth grow too long and cut into the gums, causing pain, or prevent the mouth from closing properly, which often makes the pet stop eating. Just as in people, cancer is often seen in pet rodents, especially mammary (breast) tumors in rats and mice. Rodents with signs of respiratory or GI disease or evidence of a tumor should be seen by a veterinarian who can properly diagnose and treat the underlying condition.

Osteochondritis Dissecans (OCD) in Dogs

Osteochondritis dissecans is an inflammatory condition that occurs when diseased cartilage separates from the underlying bone. It most commonly affects the shoulder joint but the elbow, hip, or knee (stifle) may also be involved. This is a developmental disease that occurs in rapidly growing large breed dogs typically between 6 and 9 months of age and tends to occur more often in male dogs. Dogs that are affected with OCD typically limp or are lame in the affected leg or legs. Several radiographs of each affected leg are necessary in order to get an accurate assessment of various bones and joints. Treatment may involve conservative medical management or surgical intervention.

Common Diseases of Box Turtles

Turtles commonly suffer from vitamin A deficiency, respiratory diseases, abscesses, shell infections and fractures, and parasites. Vitamin A deficiency occurs as a result of feeding turtles an inappropriate diet. Symptoms include a lack of appetite, lethargy, swelling of the eyelids, swelling of the ear, kidney failure, and respiratory infections. Respiratory tract infections are most often caused by bacteria. Abscesses are treated surgically. Shell infections can be challenging to treat. Gastrointestinal parasites are treated with appropriate deworming medications. Seek immediate veterinary care if there is any deviation from normal in your pet turtle.

Vitamin A deficiency (hypovitaminosis A) occurs as a result of feeding turtles an inappropriate diet. Symptoms include a lack of appetite, lethargy, swelling of the eyelids, swelling of the ear, kidney failure, and respiratory infections. Respiratory tract infections are most often caused by bacteria. Abscesses are treated surgically and may also require antibiotics. Shell infections can be challenging to treat. Gastrointestinal parasites are treated with appropriate deworming medications. Seek immediate veterinary care if there is any deviation from normal in your aquatic turtle.

Distichia or Distichiasis in Dogs

Distichiae can be an irritating eye problem for many dogs. The abnormally growing extra eyelashes can cause chronic discomfort to the eye and potential vision problems. A thorough eye examination, including fluorescein staining of the cornea and an assessment of the degree of tear production in the eyes, is usually necessary to assess the extent of any accompanying corneal injury and to rule out other causes of the dog's clinical signs. Various treatment options are available in order to help dogs live a more comfortable life. The prognosis is excellent for those dogs that do not show any clinical signs associated with their distichiae. For dogs with mild clinical signs, the likelihood that the condition can be managed with conservative treatment is good.

Brachycephalic Airway Syndrome in Dogs

Brachycephalic airway syndrome occurs in dogs that have anatomic abnormalities causing a more flat-faced appearance. These changes in anatomy cause restrictions in the dog's upper airways (including stenotic nares, elongated soft palate, nasopharyngeal turbinates, and hypoplastic trachea), and can eventually lead to everted laryngeal saccules and laryngeal collapse. Common signs of this condition are open mouth breathing and snoring, but can worsen, leading to exercise intolerance, coughing, gagging, or retching. Diagnosis of elongated soft palate, everted saccules and hypoplastic trachea requires deep sedation or general anesthesia. Dogs with this condition may require only corticosteroids, oxygen, and environmental management, but surgery to correct the palate, nares, and everted saccules may need to be performed. Prognosis is good to guarded depending on the severity of the disease but is greatly improved if the problem is noted and treated surgically in younger dogs.

Glaucoma in Cats

Glaucoma is a disease of the eye in which the pressure within the eye, called the intraocular pressure (IOP), is increased. Glaucoma is caused by inadequate drainage of aqueous fluid. Glaucoma is classified as primary or secondary. High intraocular pressure causes damage to occur in the retina and the optic nerve. Blindness can occur very quickly unless the increased IOP is reduced. Analgesics to control the pain and medications that decrease fluid production and promote drainage are often prescribed to treat glaucoma. The prognosis depends to a degree upon the underlying cause of the glaucoma.

Blepharitis in Cats

Blepharitis means inflammation of the eyelid and can affect one or both eyes. The affected eyelid will usually be red, swollen, and itchy. Any condition that can cause irritation of the eyelids can lead to blepharitis. Common causes of blepharitis include congenital abnormalities, allergies, infections, tumors, and occasionally other inflammatory disorders. Your veterinarian will conduct an eye examination to determine the extent of the eyelid involvement. Specific treatment for blepharitis will depend on the underlying cause of the disorder and the prognosis depends entirely on the cause.

Luxating Patella in Cats

The patella connects the femur and the tibia and is normally located in a groove called the trochlear groove found at the end of the femur. A luxating patella is a kneecap that 'pops out' or moves out of its normal location. The patella will luxate or slip out of the groove during extension of the leg if the trochlear groove is too shallow, if the cat is bow-legged or cow-hocked, or if the point of attachment on the tibia is off-center. There are 4 grades of patellar luxation, and a higher grade means that the condition is more severe. Your veterinarian will diagnose a luxating patella by feeling the displaced kneecap during palpation of the leg. A luxating patella can be corrected surgically, especially if the patella luxates frequently. If your veterinarian performs surgery before arthritis or other knee injury occurs, the prognosis is excellent.

Struvite Bladder Stones in Dogs

One of the more common bladder stones found in dogs is composed of magnesium ammonium phosphate hexahydrate (also known as struvite stones). Struvite bladder stones usually form as a complication of a bladder infection caused by bacteria, and if the urine becomes exceptionally concentrated and acidic. The most common signs that a dog has bladder stones are hematuria and dysuria. There are three primary treatment strategies for struvite bladder stones: 1) feeding a special diet to dissolve the stone(s), 2) non-surgical removal by urohydropropulsion and 3) surgical removal. Dogs that have experienced struvite bladder stones will often be fed a therapeutic diet for life.

Cystine Bladder Stones in Dogs

Cystine bladder stones appear to be the result of a genetic abnormality that prevents a dog from reabsorbing cystine from the kidneys. While bladder stones in general are somewhat common in dogs, cystine bladder stones are rare. Your veterinarian may be able to palpate the stones or may need to perform imaging studies such as a bladder ultrasound or a contrast radiographic study. There are two primary treatment strategies for treating cystine bladder stones in dogs: urohydropropulsion or surgical removal. Dogs that have developed cystine bladder stones in the past will often be fed a therapeutic diet for life. Unfortunately, cystine stones have a high rate of recurrence, despite careful attention to diet and lifestyle.

Calcium Oxalate Bladder Stones in Dogs

One of the more common uroliths in the dog is composed of calcium oxalate crystals. Current research indicates that urine high in calcium, citrates, or oxalates and is acidic predisposes a pet to developing calcium oxalate urinary crystals and stones. The most common signs that a dog has bladder stones are hematuria and dysuria. The only way to be sure that a bladder stone is made of calcium oxalate is to have the stone analyzed at a veterinary referral laboratory. Unfortunately, calcium oxalate stones have a somewhat high rate of recurrence, despite careful attention to diet and lifestyle.

Burr Tongue in Dogs

Burr tongue is the common name for burdock tongue (also called granular stomatitis or granulomatous glossitis) caused by ingestion of the burrs from the burdock plant. Burr tongue is most commonly seen in long-haired dogs when they accidentally traumatize their tongue and mouth on the burrs during grooming. The hooked scales of the burrs become embedded in the tongue and gums and cause an intense foreign body reaction. Affected dogs often have small red bumps on the tip and edges of their tongue, front of the lips and gums, and occasionally the base of the nose. Based on the severity of the condition, treatment ranges from letting the injuries heal on their own to administering antibiotics and pain medications, to surgical intervention.

Spaying in Rats

An ovariohysterectomy is often referred to as a spay or spaying. It is a surgical procedure in which the ovaries and uterus are removed completely to sterilize or render a female animal infertile. Some veterinarians will perform an ovariectomy on rats, in which just the ovaries are removed. Spaying significantly minimizes the risk of ovarian, uterine, breast, and pituitary gland cancers in rats. Ideally, most rats are spayed between four and six months of age. Your veterinarian may recommend pre-surgical blood tests before surgery. In general, complications are rare with this surgery. However, as with any anesthetic or surgical procedure, in any species, there is always a small risk associated with being anesthetized. Most rats will experience no adverse effects following spaying, and in general, spaying is recommended for all healthy, young rats to prevent future health problems.

Cranial Cruciate Ligament Repair: Extracapsular Repair and TightRope Procedure

The traditional ECLS technique is the oldest surgical correction for cruciate ligament injury in dogs. The name of the procedure originates from the fact that the joint is stabilized outside the joint capsule (externally). CCL repair surgery typically consists of an initial examination of the inside of the knee. This examination may either be done by opening the joint capsule and looking inside or by using an arthroscope. Both the traditional ECLS and Tight Rope® procedures are considered extracapsular or external repairs of CCL injury. Both yield similar results with similarly low risks.

Cranial Cruciate Ligament Repair: Tibial Plateau Leveling Osteotomy and Tibial Tuberosity Advancement

One of the most common injuries to the knee of dogs is tearing of the cranial cruciate ligament (CCL). This ligament is similar to the anterior cruciate ligament (ACL) in humans. There are actually two cruciate ligaments inside the knee: the cranial cruciate ligament and caudal cruciate ligament. They are called cruciate because they cross over each other inside the middle of the knee.

Total Hip Replacement in Dogs

The hip joint is a ball and socket joint. The ball is at the top of the thigh bone (femur), and the socket (acetabulum) is in the pelvis. Total hip replacement surgery removes and replaces both the ball and socket with prostheses. Most commonly, dogs having a total hip replacement will have a thorough examination and a blood screening profile to prepare for general anesthesia. Post-surgery, the dog will spend 3 to 5 days in the hospital to get the healing off to a good start. Approximately 90 - 95% of dogs who have a total hip replacement do very well and have excellent post-surgical function.

Patent Ductus Arteriosus in Dogs

The ductus arteriosus is an arterial shunt between the aorta and the pulmonary artery. Patent ductus arteriosus is a heart defect that occurs when the ductus arteriosus fails to close down at birth. If the ductus arteriosus fails to close properly after birth, the difference in pressure between the pulmonary artery and the aorta means that the blood will take the path of least resistance and flow from the aorta through the patent ductus arteriosus into the pulmonary artery, needlessly recirculating this oxygenated blood back to the lungs. The larger the PDA is, the more blood will be shunted through it, causing more significant signs. A PDA will usually be diagnosed when your veterinarian hears a continuous heart murmur during a routine physical examination of your puppy. The goal of treatment for a forward flowing PDA is to stop the blood flowing through the shunt. Your veterinarian will refer you to a veterinary cardiovascular surgeon, who will determine the optimal treatment for your dog. Provided that the condition is treated before heart failure develops, the success rate associated with surgical closure is very high and the prognosis for a normal life after surgery is excellent.+

Ulcerative Keratitis in Cats

Ulcerative keratitis is a kind of inflammation that occurs in the cornea of the eye. Some breeds seem to develop them more commonly, particularly Himalayan, Persian, and Burmese cats. The signs of ulcerative keratitis depend somewhat on the cause and how long the condition has been present. There are many potential causes of ulcerative keratitis, including trauma, infection, and abnormal tear production. Antibiotic ointment or drops will be prescribed, and it is important to prevent additional trauma to the cornea. Superficial corneal ulcers typically heal within 5 to 7 days.

Collie Eye Anomaly

Collie Eye Anomaly (CEA) is a genetic mutation affecting many breeds that causes developmental defects in the eye that can lead to vision deficits or blindness. This defect can be diagnosed by a veterinary ophthalmologist between 6 and 8 weeks of age by visualizing spots of choroidal hypoplasia or a colobomas . It can be associated with microphthalmia or enophthalmia. It can lead to retinal detachment and blindness. Although laser repair of partial retinal detachments can be attempted if detected in early stages, there is generally no treatment for CEA. Vision varies depending on the extent of the lesions and some dogs will become blind. Prevention requires not breeding animals that carry the mutation and this can be achieved through genetic testing of breeding dogs.

Porcupine Quills in Dogs and Their Dangers

Porcupines are the third largest rodent and live in many rural areas in North America. They are not aggressive, but they happily defend themselves, their offspring, and their dens if needed. Porcupine quills can puncture the skin and move through muscle, ultimately penetrating into body cavities and internal organs. Do not cut quills; cutting the shaft makes the quill splinter more easily which ultimately makes it harder to remove. Do not attempt to remove quills yourself. Seek immediate veterinary care if your dog is quilled. Sedation or anesthesia is required to remove quills safely. The best defense against porcupine quills is prevention. Avoid allowing the dogs to roam at dusk or after dark.

Perineal Urethrostomy Surgery in Cats

A perineal urethrostomy (PU) is a surgical procedure that is most commonly performed on male cats with a urinary obstruction. Male cats develop urinary obstructions much more readily than female cats, due to differences in urinary tract anatomy between the two sexes. A PU creates a new urinary opening that decreases the length of the urethra and allows urine to bypass this narrowed region. Less commonly, PU may also be performed in cats with severe urethral trauma. After surgery, your cat will be required to wear an Elizabethan collar (e-collar) to prevent self-trauma to the surgical site.

Xanthine Bladder Stones in Dogs

Xanthine bladder stones are an uncommon type of urinary stone that can occur in both dogs and cats. Xanthine is produced when certain types of proteins are broken down within the body; while most dogs further breakdown xanthine to other substances that are more easily excreted, some pets are deficient in an enzyme that is required for this breakdown to occur. These pets develop elevated levels of xanthine in the urine, resulting in xanthine stones forming within the urinary tract. Xanthine urinary tract stones are typically removed surgically. Affected dogs require long-term care to prevent recurrence of xanthine urinary tract stones.

Oxalate Bladder Stones in Cats

Oxalate bladder stones are composed of a mineral called calcium oxalate. Over the past 40 years the incidence over oxalate bladder stones has increased in cats. Cats are more likely to develop oxalate stones when their urine contains high levels of calcium and oxalate. In some cases, this is also associated with high blood calcium levels. Additionally, a low urine pH promotes the formation of oxalate stones. Bladder stones can cause significant inflammation and irritation of the bladder wall. Signs may include frequent urination, straining to urinate, blood in the urine, and urinating outside of the litterbox. Treatment of oxalate stones usually requires surgical removal, known as a cystotomy or less commonly may be removed via a process known as cystoscopy. Your cat will require ongoing management.

If your cat is having urinary issues, your veterinarian will first recommend a urinalysis. Blood tests, abdominal radiographs, and ultrasound may also be recommended. Medical dissolution and surgical removal are two categories of treatment. Cats who have developed struvite bladder stones are likely to experience a recurrence later in life, unless the conditions that led to the formation of stones can be corrected.
