We’re excited to share some big news! ❤️

Brookline Animal Hospital is thrilled to announce our most recent partnership with Second Chance Ranch Rescue NH and we couldn’t be more excited to begin this journey of helping deserving dogs find their forever homes. Giving back to animals in need is incredibly important to us and this will allow us to make an even bigger impact.

We’re especially excited to introduce Blue, the first dog we are sponsoring! We are matching her adoption fee to help her get home faster, the donation will go directly towards Blue’s care while up for adoption.

Blue is a 9 year young Pitbull mix who is FULL of life and is looking for a home where she can be the only pet. She is affectionate, loving and especially loyal. Our management team was welcomed by Blue with open paws when we toured the rescue!

If you’re looking for a loving companion who is young at heart Blue could be your perfect match 💙

Please help us kick off this exciting journey by sharing Blues story and reach out to Second Chance Ranch Rescue to learn more about adopting this amazing girl or making a donation in her name.

Thank you for your continued support, lets try to ring in the new year by getting Blue home 💙

We were notified of a black and white cat that was deceased and appeared to have been struck by a vehicle next to Brookline Animal Hospital.

The cat did not have a microchip or identification tag. If you believe this may be your pet, or know potential owners please reach out to us directly.

The remains are safe with us and will be held through the weekend in case an owner comes forward. We will provide the cat with respectful aftercare. Our hearts go out to anyone missing their beloved companion. ❤️

Our Story

After being a veterinarian for 21 years and working in the Nashua area for 20 years, Margaret Monachelli opened Brookline Animal Hospital in June, 2012. We opened our doors with one veterinarian, two technicians, and the help of Margaret’s two daughters.

From the beginning our goal has been to provide exceptional veterinary care in a warm and comfortable environment. Our clients saw that we were sincere in fulfilling this goal and we were fortunate to be well received by the people of Brookline, NH. In addition, many of Dr. Monachelli’s former clients followed her to her new practice.

It has already been 8 years since we opened our doors! We recently welcomed our newest associate, Dr. Amy Gates. She joins Margaret Monachelli, D.V.M., MaryEllen Blake V.M.D, and C.J. Churchill, D.V.M. That makes four exceptional veterinarians with training from Cornell University, University of Pennsylvania and Tufts University, along with a total of 78 years of experience!

Brookline Animal Hospital is a full service veterinary hospital for small animals. We provide preventive care and consultations along with diagnostics and treatment for sick or injured animals. We have digital radiography, ultrasound, and a complete in-house laboratory. We have a surgical facility and can perform most surgical veterinary procedures by our staff veterinarians or by our surgical specialist, Dr. Geoffry Clark. We have a dental suite where we perform dental cleanings, full mouth dental radiography, and oral surgery. We have a board certified cardiologist that regularly visits our practice to evaluate and treat cardiac patients. We provide 24 hour care for hospitalized patients.
