This is a hereditary, developmental disease that affects the hip joints of dogs. Certain breeds are more likely to be affected than others. Although its occurrence in large and giant breeds is well documented, there is evidence that it may also be present in smaller breed dogs and cats as well.
Poor conformation of the hip and thigh bone structures result in a 'looseness' of this ball and socket joint. This looseness allows the ball part of the joint to move in the socket, instead of remaining stable as it should in a healthy, normal, tight fit. This abnormal movement can create wear and tear in the joint, leading to arthritis. Although signs of the disease do not typically appear until after the dog matures, puppies as young as five to six months can be affected. Hip pain, stiffness, abnormal gait patterns, an
audible 'clicking' sound while walking, and a reluctance to exercise are all possible signs of hip dysplasia.
The disease is usually diagnosed using radiographs, or x-rays. The treatment for this condition is primarily surgical. In one type of procedure, the Triple Pelvic Osteotomy, or TPO, the bones of the pelvis are cut apart and rotated to more correct positions. In Total Hip Replacement (THR) procedures, a dog's diseased hip joints are replaced with prosthetic ones. The goal of both surgeries is to provide your pet with some measure of normal activity and function and to reduce the pain associated with the condition. A very high level of success is reported with these surgeries. However, as with all major procedures, it is very important to follow your veterinary surgeon's recommendations regarding recovery and rehabilitation.
