24/7 Advice

We are proud to offer our clients 24/7 medical advice and assistance via our On-Call doctor. Both Dr. Hollengreen and Dr. Hanlon alternate as the On-Call doctor and one of them will be available to help you if you have an urgent medical question about your pet after hours. You may call our main office number (603-889-5442) and you will be transferred to our answering service. They will assist you with either leaving the hospital a message that can be dealt with on the next business day OR you may opt to have the doctor that is On-Call paged to call you back. Please keep in mind that this service is intended only for current patients of our practice. 


Staff veterinarians perform most surgeries, and we work closely with a board-certified surgeon who is available for complex procedures. Internal medicine specialists are available to perform cardiac and abdominal ultrasounds at our hospital. Our hospital collaborates regularly with area specialists, and we may advise referral if your pet needs advanced care or internal medicine evaluation.


We are thrilled to be able to offer our patients visits with local traveling specialists to help us provide advanced care for patients that include Cardiology, Internal Medicine and Orthopedics. Abdominal ultrasounds as well as Cardiac ultrasounds are available to schedule regularly. When necessary, we will refer cases to surrounding specialty hospitals for more advanced or critical care. 


Boarding services are available for pets that require extra monitoring, including pets needing treatment for diabetes, renal failure, seizures, heart disease, arthritis and recovery from surgery or trauma. Drop offs and pick ups must be arranged during business hours and will not be available on weekends. Boarding patients are taken outside to use the bathroom regularly and will be evaluated in rounds every week-day morning by our on-staff doctors. We ask that you bring any food and medications your pet is currently on when dropping them off for boarding.

If you are interested in having your pet board with us, please give us a call with any questions or to schedule their stay!
