Business Hours

Mon-Sun: Open 24 hours

The team at VCA 404, which includes board-certified specialists, will work with you and your family veterinarian to offer you the most advanced diagnostic and treatment options available. When emergencies occur, we're here for you 24/7. What could be more important?

We ask that you arrive 15 minutes prior to your scheduled appointment to allow time to complete our patient check-in procedures. Please ensure all documentation from your family veterinarian has been sent to us before your arrival when possible. If you are transporting this information yourself, please let our client care team know what you have brought with you when you arrive. Our team will also ask for a current list of the medication(s) and food your pet is currently receiving. Please have this information available.

Once you have been checked into our hospital, you and your pet will meet with one of our veterinary technicians and/or veterinarians, who will take a thorough history of your pet’s condition and examine your pet. Once the physical examination is complete, a diagnostic plan will be outlined to further specify what is the best course of action for your pet.


In almost every case, further testing is required to arrive at a specific diagnosis of your pet’s condition. Testing may include x-rays, blood work, urinalysis, biopsies or more. In some cases, multiple departments/specialists may work together to get a better overall picture of your pet’s health and determine the best treatment plan for you and your pet. We understand that there is often a lot of information brought forward regarding diagnostic tests and findings. If you require clarification on anything presented to you, please ask questions; we’re here to help.

All diagnostic tests and findings are included in your pet’s medical record and provided to your family veterinarian. We will also provide you with your own copy of take-home instructions, including any/all significant findings.

Admitting Your Pet

Should your pet require hospitalization or if they are being admitted to the hospital, there are a few guidelines to follow. For planned admissions for anesthesia, surgery, or various other procedures, you may be directed to withhold food for 12 hours. Water is usually allowed to be given to your pet until admission, but please ask a team member for confirmation.

At admission, we will ask for details, including best contact numbers, details of medications, food allergies, pet’s overall health status for the day of the procedure etc. Please note, if your pet has ongoing medications, they can usually be given the day of surgery unless they are given with food or were recommended not to be given by your veterinarian. If you have any doubts, please ask a member of our team. We encourage you to bring any ongoing medications with you, and our team will advise you which medications should be left with us to be administered to your pet during their stay. Some pets may be required to stay with us for a number of days. Throughout their time here, your pet will receive round the clock care from our team. We will provide you with updates at least once a day. However, you can call for nursing updates a couple of times throughout the day. If any complications or significant changes occur during your pet’s stay, you will be informed immediately. 
Discharging Your Pet

All pets discharged from the hospital will be presented with take-home instructions. These instructions will include all of the details discussed with you during your pet’s visit, any significant findings/results, and any medications or procedures you will be required to perform once your pet is at home. We will review your take-home instructions with you. Questions are encouraged. We also encourage clients to call the hospital if questions should arise at a later time.
