I was told to give my cat Metacam, a drug that says oral for dogs only on the package. On the third day she stopped eating and drinking. She was vomiting bile and lethargic.(she had to get fluids and has improved a little but could be eating better) Started doing research on my own and found out that the drug causes kidney failure in cats. I wish I had read the box first instead of blindly trusting the female vet who prescribed it. We have been going to this place since I was a child so I'm sad I had to write this review. I don't think I will be going back as long as she works there. Read Less

I moved to Hamilton Township 12 years ago and Mercer Animal Hospital became my Veterinary Hospital. They brought my animals through some very difficult times in a highly professional and sensitive manner. They care about the pets and their families. The Doctors and entire Staff show genuine concern for my Dogs and Cats and are truly passionate about animals. Thank you. Read Less

My family has come to Mercerville Animal Hospital since "Old" Dr. Wm. Carter was practicing, God rest his sweet soul. The Carter family and their entire staff are true animal lovers and want the best for our furr-babies, just as much as we do! I wouldn't think of trusting my babies to anyone else. Thank you MAH for all you do Read Less

I gave the Mercerville Animal Hospital four stars instead of five because their front desk can be a little ditzy and we had the same experience as the previous reviewer with the lady vet--unnecessary tests and the wrong medication. Fortunately, we only saw her once and have been seeing Dr. Stuart since. We LOVE, LOVE, LOVE Dr. Stuart and so does our dog. He really takes the time to listen to us and has a great "bedside" manner with her. She actually looks forward to going to see him. His techs are great with her too. Dr. Stuart always makes sure we understand our treatment options and keeps both our dogs health and our budget in mind. Would recommend him in a heartbeat. Read Less

We switched over to Mercerville a couple of years back after seeing the difference in just an ordinary checkup between here and another vet's office on the other side of town.  The location itself is slightly ragged around the edges, but for regular services the doctors there seem to put more effort and care into their examinations and diagnosis.  There have been a couple of times where we've needed to go into PA to the CARES animal hospital for emergencies and specialty care, but for the everyday stuff, we're very happy with Mercerville.  The only downside is that it seems we've had a different doctor every time I've taken the dogs in for a checkup.  I'd like to have a little more consistency in our doctor, so that they can build a history with our dogs and us.

I've been going to the Drs. Carter for over 45 years. They were the most knowledgeable and reasonably priced and never tried to talk you into expensive procedures. The oldest Dr. Carter would even suggest home remedies so my pets would not need expensive medicines. Well times change and so has this practice. There is now a new female doctor there who pushes expensive procedures, talks you into unnecessary tests, gives incorrect medication so you have to return multiple times for the same issue. And she is very unprofessional in that she bad mouths other doctors and brags about how she gets free services for her pet as a professional courtesy because she's a doctor. Sadly, I am looking for a new vet. Read Less

Mercerville Animal Hospital is the only hospital I trust. They have helped me with rescues, strays and mistaken diagnosis from other vets. We are always seen quickly and all the staff is friendly and very knowledgeable. We love the Drs they are all so patient, friendly and spot on with everything. They have great office hours and when we walk in we are seen immediately. 10  stars to this group. Read Less

The accuracy of diagnosis depends on the vet you get. Dr. Stewart is excellent and is now the only dr there I request. I've brought in my dog before to a different dr there who said he was scratching from allergies. Turned out he was infested with fleas even with frontline. Those types of scenarios have occurred over the years. So I have found that I will only request dr. Stewart. He is on his game, explains everything in detail, and I trust him with my pets. Read Less

This is not a bad animal hospital, at all. I appreciate that it's a family business, but I'm much happier when we see Dr. Carter Jr. or his wife. The elder Dr. Carter is a competent doctor, but does not have people skills, and he's rather "business only" with the animals, as well.But, I am endlessly grateful that they work with a local rescue organization, Animals In Distress, and will sterilize and vaccinate stray/feral cats at no charge to the folks who bring them in (with prior approval from AID), to be released back to their colonies, or adopted out. The front desk staff, in these instances, always tries to bill me - even though I've mentioned the AID funding multiple times - so they aren't the most organized, but it's a small inconvenience, and I'm happy to keep cats out of the kill shelters in the area. I've brought in about 10 feral/stray cats over the years and have been happy with the level of care.I also brought in my good old girl, Lacey, when she was nearly 15 years old - she had always had a little wart on her neck, and it grew over the years to the point it was about the size of a small mushroom (but much uglier) in the last year of her life. I was irritated that vets she saw over the years said "it's just cosmetic, leave it be," and then she happened to scratch it so bad that it would not stop bleeding, as a geriatric dog. But how could they know this would happen, I suppose. Dr. Carter Jr. got us in right away and took care of it, saving me the trouble and expense of taking her to the emergency animal hospital. Despite the fact the lump was attached to her neck by a small amount of tissue, there were 4 arteries feeding the nasty thing. He got her stitched in no time, without too much trauma to my poor old girl.Their prices are on the high side, but not as bad as some others (looking at you, Banfield).So, in short, not a bad place, but be prepared for scatterbrained help at the front, slightly inflated (but not offensive) prices, and if you have a choice of doctors, opt for Junior or his wife.

I have been using Mercerville for all my dogs needs for years. Recently my dog Zeus got hurt pretty bad and Dr Carter and Staff have gone above and beyond in caring for him. I personally thank them for take such good care of my fur family ALWAYS! Read Less

Took my Princess for her yearly checkup and to have her teeth checked too. I knew she needed to have them cleaned. Dr. Carter came out and greeted me immediately and took us back in the exam room. He was so great and answered all my questions. She needed to have a tooth pulled and have her teeth cleaned and they did it right away. I was so happy and they took such great care of her. She is doing fine tonight. So glad I went there. Great office, thank you everyone for taking such wonderful care of us and being so efficient. (P.S. - This was our first time at Mercerville Animal Hospital.) Dr. Carter your the best! : ) Read Less

I have been coming here for about 6 years with 3 different dogs. The level of care is adequate, the facility is a bit run down but also adequate. Here is the problem, they overbook to the point that a 45-60 minute wait is a matter of routine. I have waited in excess of 50 minutes on several occasions and I am tired of this treatment. I walked out today after waiting 45 minutes and I doubt i'll be back. This practice needs to respect the time of thier clientele. When I left without being seen I was told that an emergency had affected the schedule (I must have a knack for scheduling around "emergencys"). In the future, kindly call your clients and let them know that thier appointment will be delayed. Read Less

I decided to try Mercerville Animal Hospital, as I found the Animal Hospital near my home (and the Princeton Junction train station) to be too expensive. I was very pleased with Mercerville. It's a small office (with low overhead) and more importantly, the vets are VERY COMPETENT. Doctor Stewart immediately diagnosed a serious condition with my dog on our first visit, without the need for a battery of tests. (This issue had been misdiagnosed by a vet I had visited while vacationing in Miami three weeks prior.) I also appreciated his direct yet compassionate style. I wish I had discovered Mercerville earlier. I find that too many larger clinics are going the way of human hospitals, with a business focus on maximizing revenue. At Mercerville, it is clear that the Vets there are in charge, they can stay true to the ideals which drove them to become Vets, and they truly care about your pet. Read Less

I have taken my pets to the Mercerville Animal Hospital for over 40 years.  All of the Doctors and staff have treated my dog with loving care and respect. When my family was experiencing financial difficulties, I was able to slowly pay my bill.  They have seen my dog on an emergency basis several times.  One of my friends, whose Veterinarian was out of town, raced their dog who was not breathing to Dr. Carter's office and he saved her dog.  I highly recommend the Mercerville Animal Hospital! Read Less

This practice was originally recommended to me by a friend, and my two rescue dogs have been going here for almost 8 years. They have seen all 3 Drs. Carter and Dr. Stewart (sp?) - all of whom are very caring. The Drs. always remember me and my dogs, and I love that they take the time to give my furbabies a thorough exam and to educate me. Several years ago my Golden became very ill suddenly and even the local emergency/specialty hospital was stumped. It was Dr. Carter Jr. who saved his life. I trust these guys implicitly. Read Less

Dr. William J. Carter (Sr.) is the best vet in the area for diagnosing. Even without lab work, he is always right when it comes to diagnosing and treating my dogs and cats. The only other vet that has seen my cat was Dr. Stewart. He was excellent with my very shy and nervous cat and made her feel safe. The staff is great, especially Janine. Michele runs an efficient office. I guess it is in the genes! I love Dr. Carter and hope he never retires. Read Less
