Our Services

We will always try and see you and your pet as soon as we can.

The Vets at Companion Animal Hospital know it can be an ordeal to find a new veterinarian who can take on your pet as a patient in a timely manner.  Our Groton animal hospital makes it as easy as possible, allowing for same-day sick or medical cases whenever we're able for patients both new and old.

Our in-house diagnostic lab provides quick results and treatment options.

Our cutting-edge in-house lab allows us to conduct testing like radiography, ultrasound, and MRI rapidly and accurately directly on-site. Time is often of the essence when treating serious illness and injury, and so we aim to provide care as efficiently as possible using these advanced diagnostic tools.
