What To Do In A Pet Emergency

If you know what you can expect at our emergency veterinary clinic, the process will be easier for both you and your pet. Here are the steps to follow if you have an emergency:

STEP 1
Call Ahead If You Can

We understand that in an emergency, you won't be able to call us in advance, but it's always best if you can.

STEP 2
Get To Our Office Right Away

You'll be shown to an exam room by one of our team members. You'll be asked to complete our New Patient Form. A veterinary technician will triage your pet, then a veterinarian will conduct a full exam.

STEP 3
Determine Treatment

Once one of our highly trained emergency veterinarians has examined your pet, he or she will create a treatment plan, so your pet will receive the best possible treatment. We will update your primary care veterinarian on your pet's medical status and history to ensure your pet receives seamless, integrated care.
