At Montowese Veterinary Clinic, our goal is to be an extension of your pet's family, offering our compassion, medical expertise, and support throughout their life. Since 1977, our animal hospital has made companion animal health a priority. Today, our veterinarian continues to use every resource available to give the dogs and cats of North Haven and beyond the best veterinary care possible.

We're focused on offering the most important preventative care services to your pet in a friendly, low-stress environment, and providing more intensive services through an affiliated practice located just minutes away. Dr. Mendillo became the owner of Montowese Veterinary Clinic in 2019.
Services
We strive to make Montowese Veterinary Clinic in North Haven, CT a place that doesn't feel like your typical animal hospital. While we are proud to offer our clients and patients exceptional service and access to some of the most advanced veterinary technology, our main priority is cultivating a calm, friendly atmosphere.
Keeping your pet healthy for life is our highest priority here in North Haven. We use all the resources available to us to ensure that they continue to enjoy the best quality of life possible while in your care. Annual physical exams are an essential part of your pet's lifelong care regimen.

These exams typically include blood and fecal testing to screen for disease and parasites, recommended vaccinations, and a thorough evaluation and discussion about your pet's diet, physical activity, behavior, and much more.Our clinic provides care that is tailored to your pet's age, overall condition, and medical history.
Pet exams are extremely important for dogs and cats. During their journey through life, these check ups are essentially mile markers where we assess your pet's condition and, if needed, offer suggestions to improve their health and quality of life. Regardless of age, dogs and cats should be examined regularly so we can check for disease and maintain their protection against future infection.
At Montowese Veterinary Clinic, we believe that every dog and cat living in North Haven and surrounding communities should be spayed or neutered before they reach maturity. Schedule your pet's spay or neuter surgery with us or set up a consultation to discuss their options. At first glance, spay and neuter surgeries seem to go against the laws of nature, which might beg the question: How is spaying/neutering better for an animal's health?
First and foremost, cat and dog vaccinations protect individual pets from a variety of diseases that can do them serious harm. But that's not all--vaccinating your pet also reduces the spread of these diseases throughout North Haven, CT and surrounding areas. Both humans and their pets can enjoy a healthier, safer existence with the help of vaccines for dogs and cats.

I made an appointment for my kitty. A first time appointment requires a deposit of 50 dollars. Sadly, two weeks before the appointment we found out my kitty was sick, and we had to let her go. I was happy to see that montowese gladly returned the deposit for the appointment that ultimately was not needed. I appreciate their understanding in this sad situation. They are great, and I highly recommend them. All my previous pets growing up went there, and I just recently had to let go of my dog too. They were kind, and gentle, and really lovely to us. They are good people there.

Having recently moved to North Haven, we were so lucky to find such an exceptional vet right around the corner from us. I haven't experienced this at previous vets, but I sure have here which I love - the staff greets every person and pet with so much enthusiasm. They're really outstanding

I have an elderly dog who needed a vet who would give her the attention she needs. I am so glad we chose to see Dr.Mendillo. She took the time to help me get her on a detailed plan and was so patient with me and all of my questions. Highly recommend this place. Staff are very kind and helpful. So thankful to a friend who recommended this practice to me.

Came in 20 minutes early and was told I would be next and that there was only 1 person ahead of me. That made sense because it would take roughly that amount of time to take care of someone that was there before me so I waited with no issues. I told them my cat was sick overnight (hard to breathe and limping) as well and when my appointment time came they told me they will take care of 3 more people before me and said it was because they arrived after their appointment time. I witnessed healthy animals who’s owners were late go in before my sick cat during MY appointment time. When I expressed

I would like to thank Dr. Mendillo and staff for their professionalism and concern. I called yesterday morning to make an appointment for my very sick 12-year-old cat, Chiquito. Though I was told Dr. Mendillo was booked all day, she still agreed to see Chiquito last minute. She spent almost an hour with my pet, getting blood and urine samples and performing a series of other tests. When I got a call back from Dr. Mendillo, she insisted that Chiquito be taken to the hospital immediately. Initially, I was reluctant to take her right away and was even willing to wait for the blood test results to

Our family has just loved being welcomed into this practice! From day 1 we have felt comfortable and at ease with our pets being in their care. They treated us like family and our pets like they were their own. They are always so kind to our pets and answer all of our questions, no matter how silly they may be. Dr. Mendillo and her staff are knowledgeable, helpful, and very friendly, which is hard to come by these days. We are so happy to have found Montowese Vet and we will never look anywhere else!
