We called to hopefully get our dog who’s vet was booked an emergency visit for concerning behavior. The website lists emergency services, so we figured it was a safe bet. The receptionist said they do not offer emergency services. It’s called Companion Animal Hospital… but the receptionist also told us that they’re not a hospital. Make that make sense. False advertising at its finest when people are at their most fragile.

Edit: After taking some time to reflect, I realize my original review may not have been completely fair. I wrote it while I was scared, upset, and heartbroken over what was happening with my dog. He means more to me than people who aren't animal lovers may understand, and my emotions got the best of me.
To be clear, no one at the hospital asked me to write this update. This was entirely my decision. While I still feel some of my concerns about communication are valid, they have always been kind to both me and my dog, and my original review didn't fully reflect that.
I considered deleting the review, but I felt it was more honest to acknowledge where I was unfair. Looking back, writing a review while I was so emotional wasn't the best decision.
I do plan on bringing my dog back because I want what's best for him, and I hope we can move forward with better communication and continue working together to help him.

I've been bringing my dog to Companion Animal Hospital in Groton for a persistent cough/retching issue with nasal congestion.
At the first visit, several diagnostic tests, including X-rays and blood work, were recommended. Because of the cost, I started with blood work. The results were normal, and my dog was prescribed an antibiotic and cough medication. He improved while on the medication, but his symptoms returned shortly after it ended.
About 2–3 weeks later, I saw a different doctor, who believed my dog might have a tracheal collapse, which is common in small breeds. The discussion focused heavily on diagnostics and surgery, but I felt there was very little conversation about supportive care or ways to help manage his symptoms at home.
When I mentioned that my dog has insurance, the estimate for the recommended testing increased noticeably, despite including essentially the same diagnostics. When I asked for clarification, I didn't receive a clear explanation.
My biggest concern was the lack of guidance on managing his condition day to day. I understand that additional testing is often necessary, but I left feeling the focus was on diagnostics rather than a collaborative plan that also addressed symptom management. As this was my third visit and I had followed prior recommendations, the comment that I was "not in the position" to move forward with testing felt discouraging.
The medications were adjusted appropriately, but I ultimately left feeling unsupported in caring for my dog at home.
At the time, I felt I would not be returning because I was disappointed with the communication and overall experience.

The team, especially Dr. Brown, is just exceptional. I’m so grateful for them and the attention and care they gave my little Fern. I would recommend Companion in a heartbeat!

If I could give this place zero stars I would. They are more focused on money than actually caring for animals. I was incorrectly told my dog hadn’t been seen in over a year so they could justify charging me for an exam just to get her routine yearly allergy shot. When I proved that wasn’t true, they came up with another excuse.
Every single visit turns into an attempt to add more unnecessary charges to my bill, even when I’ve clearly said no. It feels very dishonest and pushy.
I would not recommend this animal hospital. Find a vet that actually cares about your pet—not just your wallet.
