Called a couple weeks ago because one of my dogs was sick, we got in that very same day which used to be par for the course and what made them a good animal hospital. Today, Tried to make an appointment for my other dog who's leg is bothering her and they can't see her for 3 weeks...Really? It was explained what was going on, she might be in pain but 3 weeks? Why? This place is hit or miss, it used to be consistent quality care but now that seems to have slipped.

Companion Animal Hospital has been a grade A experience every time I've gone. They treat my cat well and help address any concerns I have with her while also educating me further on any questions I have. Would definitely recommend to anyone who needs a reliable and caring vet team for their pet.

The entire staff are warm and compassionate. They were extremely compassionate with our dog's end of life. They allowed my son and I to stay with our dog and see him off to the other side of the rainbow. Thank you all for your kindness!

You can tell the staff at Companion Animal Hospital really love animals and have a lot of compassion for the human companions. This photo is of my Violet exploring the exam room last month while we waited for… Dr. Jensen, and she felt a little more at ease that way. Dr. Jensen and Faun answered all my questions with kindness and good humor while Violet was shaking ear cleaning solution all over them! When I brought her back for dental work, I got a thorough update from Dr. Jensen after the procedure, and the bill actually came in a little under the estimate, so there’s no trickery

Companion Animal Hospital was able to catch the heart worm that has gone undiagnosed in my cat for several months. Dr Jensen recommend the test when I suspected he had asthma and I am so incredibly thankful to finally know what’s been causing him so much trouble.

Staff are great. From the vet docs, techs and the front desk staff. So much care into each and every trip I make for our cat Bobby and pupper Magdalena. I live in Norwich and refuse to get seen by the Veterinary Clinic because I love Companion Animal Hospital

This past Saturday, our 11-year-old dog went to Companion due to difficulty breathing and laying down Friday evening. While at Companion, when my dog had X rays done, there was no radiologist to read them. From 9:40-1:45 they could not find a radiologist. The vet wanted them to be read because what was seen could have been two different diagnoses.… He could not stand. He could not eat. We were told to not take him to Ocean State as they would turn us away. According to our text messages with her, she was still trying to find a radiologist at 1:30 and discuss his case and a possible transfer

CAH has been the most empathetic local vet. They helped me learn what my new kitten needed, and also were on top of everything when it turned out that he had FIP and passed suddenly. When I got another cat, they showed nothing but gentleness and compassion when I struggled with not being able to come into the appt due to restrictions. They never once brushed off my concerns and fully understood that my fears were associated with a previous loss. The admin staff also were so patient fielding my calls and insurance questions. I never have any concerns about the treatment of myself or my furry family

I have a dog who is absolutely terrified by even pulling up to any vet parking lot. Megan and Dr. Bender we’re extremely compassionate and intelligent in getting my dog, Luke, into the exam room and while handling him. They took extra time to make sure he felt comfortable and wasn’t being forced into anything. I’m so happy I went to Companion Animal Hospital and will always go there from now on.

I highly recommend Companion Animal Hospital. I am newer to the area and my dog, Kacey’s health was quickly declining. I called and was put on a waiting list and was seen within 48 hours. The care Kacey has… received since then has been the best vet care she has ever gotten. Dr DeWolf and staff have gone above and beyond to teach me how to care for a dog with diabetes, they check in with me, they answer my questions; I am very thankful for them everyday.

If I were asked a few months ago if I were happy with my service here, I would have answered with a solid yes. After moving to CT, I was very loyal to this clinic for my dogs care for over 9 years. I thought we… built a great relationship and I really thought they cared for my very loved dog. During the last few months of my dogs life, they were increasingly dismissive and cold towards us. I felt like I was put in a situation where I had to beg for my dog to get appointments to be seen. During an episode of bloody diarrhea, I called as soon as they opened and pleaded for an appointment.

Up until December 2020, I was satisfied with the services and process here. I requested a well check visit with the vet. The appointment was canceled and moved twice with little notice or reason. Once my pet was seen, we did not get a follow up call from the office with test results as requested. Eventually found out through a courtesy call that my pet may need follow up care- unsure of when or if I will ever get a call from the vet. Still no test results. If you want to stress out even more about your pet, bring them here.

I have been coming to Companion for almost 2 years. When I first started to bring my dog here straight from a shelter they never offered me a stool test and the doctor that we originally had, anytime we asked a question about crate training, her food we should buy etc. she didn't give us anything specific just gave us pamphlets. That should have been a first red flag to find a new vet. We express to them how we noticed that our dog had a really nasty cough when we first got her and we were told "it's probably just a puppy cough she'll get over it". Not even two days later

If I could give zero I would.. My regular vet was out due to family emergency. So I took her here, made an appointment but wasn't seen till 30 min after appointment time. The doctor gave us two option for care of our dog. Option one was over $800 and option 2 was $200. We opt for option 2, but when we signed the papers they had it in there contract that the price could go up 15% got everything they recommend and left. Took my dog to her vet today and he didn't understand why they prescribe her three different medications. He asked us to stop those medications because he didn't see

Just took in my dog for second visit. First visit no diagnosis but gave pain meds. 2nd visit dog is having wet cough and runny nose. They want X-rays and want me leave my dog even though I was willing to stay. but they said they were too busy call back at 2:00. I call back and dog has lung infection and they want to give antibodies and see again on a week. I go pick him up at 3:00. The X-ray office visit and meds were 290.00. However they charged additional fees for keeping dog for a day and they didn't even start him on the meds. I don't mind paying for good service. This

So disappointed with this vet's handling of a miscommunication. I've taken many cats to different vets, but this was my first time bringing a dog. I called around to get quotes for our very specific needs (just a rabies shot, which would need to be accompanied by a general physical). The woman I spoke to on the phone gave me a reasonable, specific quote, so I made the appointment. She also told me to bring a stool sample.

When I arrived at the appointment, I was happy to find the facility clean and bright. The staff were friendly and gentle with my boyfriend's nervous pup. I checked

I had to bring my 10 yr old lab there today to get put down. It was a very difficult experience for me but the staff here made it a lot easier. Dr. De Wolf and her assistant Olivia were fantastic. They made the process a lot easier, gave me all the time I needed to spend with my boy. I sincerely thank them very much. I hope nobody has to go through the agony of doing this but rest assured, this place WILL take care of you. Thanks again!!!

Hands down the best vet I've ever taken my animals to. From the receptionists to the vet techs, and doctors this team is amazing. I have two cats and two dogs that tend to get into a lot of " oopsies" CAH is always there to help and fitting in last minute appointments . The only vet team I've ever felt comfortable having to leave my animals at when they're sick. Trust me when I say this place is the best!

The vets at Companion Animal Hospital are very kind, caring, and hardworking. They took great care of my cat up until the very end, and always gave me options. My cat saw Dr. Dodd, and she was amazing. She knew that I was tight on money and couldn't do a lot of different diagnostic procedures, so she helped me decide what was best and saved me money. She also gave my cat fluids for free one time, because she knew that it would make her feel temporarily better and that my appointment was already going to be expensive.

I can't thank the vets, technicians, and receptionists at CAH enough

Earlier this year, the staff at Companion Animal Hospital took amazing care of our cat, who looked like he was on his death bed. Dr. Earl and Margaret Mummert are wonderful, caring, and compassionate doctors. We really appreciated their help and are thankful for the good care that they gave our little guy. With their care, he pulled through. We bring both of our cats to this clinic and they take great care of them. Thank you for your dedication and hard work!

This office is by far the most caring and committed for their patients and customers. My Blue has been using their day boarding system for the last few months while I was working and it was her home away from home. She was always excited to go and be with her friends at CAH. We were preparing her for the transition of transferring to Guam and once I told the Vet what we were doing, she took over and completed all the research to ensure that Blue met all the requirements necessary to enter Guam. I have nothing negative to say about this staff, all I can say is thank you for making our Blue one of

Our dear yellow lab Mario has been with Companion Animal Hospital ever since we got him in 2006. They've taken good care of him so well during his annual check ups as well as during our vacation where we board him regularly. They have been very accommodating. I'd like to give a big shout out to their receptionist Pam for being such an angel and lifesaver. We ran into traffic on our way to pick Mario up and the cut off was 2PM on a Saturday. We were running late by about 15 minutes and Pam was kind enough to wait for us so we can pick up our precious pet home. Big thanks and much

I have a cat and I have been bringing him here for check ups and vaccinations, so I cant provide a review based on surgery or emergency care. I pay $60 for check-ups, and I dont think it's that outrageous of a price, IMO. The staff, including the veterinarian, is very friendly and seem like compassionate people, which is important to me since theyre handling my fur baby. It's a clean, well maintained office too. I would recommend this office to a friend.
