Wellness Visits
As your pet matures from a puppy/kitten to an adult onto a senior, we offer comprehensive wellness strategies that will enable you and your furry friend to plan for each life stage and the unique health needs associated with each stage. A vital part of the exam is the discussion between the client and the professional care giver at MAMC.

The gradual onset of health problems in an apparently healthy pet often go unnoticed. Depending on the communication between you and your doctor an informed decision of a yearly or bi-yearly exam can be determined. Remember, your pet’s lifespan is shorter than ours. A lot can happen in 12 months.

Laboratory testing plays an integral role in the early detection of changes in your pet’s health. Diagnostic tests provide essential information by which our veterinarians can identify blood disorders, kidney and liver disease, diabetes, infection, cancer, thyroid disease and other hormonal problems.

Massachusetts Animal Medical Center laboratory provides fast and accurate information so that your pet can receive appropriate treatment immediately after arriving at the hospital. When more sophisticated testing is required, we utilize a certified veterinary laboratory offering the expertise of board certified specialists in pathology, hematology, internal medicine and radiology. For your convenience we can also schedule in-house veterinary specialists in several different fields including internal medicine and cardiology.

No procedure is routine when it comes to surgery at Massachusetts Animal Medical Center. Our team of doctors and surgical technicians provide an individualized anesthetic and pain management protocols for each pet undergoing surgery. For your pet’s safety, our operating suite is equipped with the latest in veterinary monitoring equipment including EKG, blood pressure, oxygen saturation, temperature, heart rate and respiration rate.

Massachusetts Animal Medical Center is able to perform most surgical procedures from spays and neuters to more complicated abdominal surgeries, mass removals and some orthopedic (bone and joint) procedures. We take pride in our equipment and our modern anesthesia and patient monitoring systems.

Dental disease, specifically periodontal disease, is the most common ailment affecting pet dogs and cats. At Massachusetts Animal Medical Center, we feel it is very important that our clients realize the impact dental care can have on their pets overall health.

An infection in your pet’s mouth is just like one in his or her kidney, heart, liver or lung. His body becomes stressed as it tries to chronically fight that infection. The infection can easily spread from the gums throughout the body via the bloodstream. Dental infections are responsible for about 80% of heart valve disease which result in heart murmurs.

We offer ultrasonic teeth cleaning and digital dental radiographs that provides your pet with good oral health. As an adjunct to teeth cleaning, we recommend a dental home care plan that is specifically designed to your pet’s needs.

Massachusetts Animal Medical Center carries an extensive inventory of veterinary pharmaceutical items, supplies, and medications. For the convenience of our clients we have the ability to treat your sick companions right away. We do honor requests for scripts but do not deal directly with any online pharmacies.
Prescription Diets
The treatment of many conditions often requires the feeding of specialized veterinary diets. We carry a variety of Hills Science Diet and Purina prescription foods. If you need a special item please let our staff know and we maybe able to accommodate. For our Science Diet customers we order on Mondays so please call early to get your order in.
