Veterinarian & Urgent Vet Care Serving Pet Families in Greenfield, WI, Milwaukee, WI & Surrounding Areas
Frontier Veterinary Urgent Care is here to support you and your pet if they have an urgent medical concern. We also aim to bridge the gap between primary care vets and emergency hospitals in and around Greenfield and Milwaukee, handling the urgent cases they may be too overwhelmed to handle. In short, our privately-owned and operated urgent care clinic is here for you and your pet when your primary vet can’t be.
We are a walk-in facility only, no appointment necessary! We treat our patients on a first-come, first-served basis, and in order of urgency. If you are able, please call us ahead of time to let us know you’re on your way, and to stay updated on current wait times.

Still Not Sure if Your Pet Needs Urgent Care?
If you are still unsure whether your pet needs urgent care, feel free to call our hospital so our team can answer your questions and determine the best course of treatment.
