This proactive approach helps maintain community animal health and prevent disease outbreaks.
Digital Radiology
Digital radiology provides immediate, high-resolution imaging for accurate diagnosis of internal conditions. Our system allows remote consultation with board-certified radiologists when complex cases arise. This technology enables faster treatment decisions while minimizing patient discomfort during diagnostic procedures.

Our experienced staff addresses unique health requirements through species-specific diagnostics and treatments. We provide tailored husbandry advice to help owners create appropriate living environments for exotic pets.
Prescriptions
In-house pharmacy offering essential pet medications with immediate access to treatment. For specialized needs, our online pharmacy system connects directly to patient medical records for accurate prescription fulfillment. This dual approach ensures medication convenience while maintaining proper record-keeping for ongoing care.

Oct 27, 2025 Report
Colonial Vet in Williamsburg, VA doesnt seem like they are in the business for the animals. Weve been taking our dog there for the last few years. We decided to breed her. We asked if there was anything they felt we should know. They said they would NOT advise on anything, unless we brought her in to be checked out. AND they told us if we didnt bring her in for a check up, they would not help if there were any complications during whelping. We understand the need for prenatal care, but to tell us they would not help if complications arose, didnt sit well with us. They would rather our dog suffer than to help, if needed? Not right.
