Specialty Care

Sometimes sick or injured pets need the care of a veterinary medical specialist. When that happens, VCA specialty hospitals work closely with the general practitioner veterinarians who refer cases to us in order to provide seamless veterinary care to your pet. When your pet is facing any kind of serious illness or injury, our specialty referral hospitals will provide the compassionate and expert care your beloved pet needs.

Our goal is to make sure that when you and your pet are in need that you have access to board certified specialists who are up to date on the very latest developments in their field. In our state of the art hospitals, our specialists also have access to the most sophisticated diagnostic and treatment tools and techniques from ultrasonography and endoscopy to CAT scans and even MRI.

Same-Day Veterinary Care

We understand that sometimes your pet needs to be seen sooner rather than later. To solve this problem, VCA Loomis Basin offers Same-Day Care appointments to accommodate client requests for “emergency” or “urgent” care during normal business hours or last-minute appointment requests. Same-Day Care is a much-needed service that helps keep the regularly scheduled appointments on track; however, clients may have to wait while other pets are being triaged.
