Welcome to Breton Veterinary Hospital

Your St. Marys County and Leonardtown Veterinarian

Congratulations on finding the perfect new veterinary home for your Leonardtown or St. Marys County pet! Breton Veterinary Hospital in Leonardtown, MD offers a wide range of services, from annual checkups, dental care and surgery to boarding, all administered by our caring, experienced and highly skilled staff. Your pet will know he is among friends, while you will rest assured that you're providing him the highest standard of veterinary care in all of southern Maryland -- including Leonardtown, Hollywood, Lexington Park, Callaway, and the rest of St. Marys County.

We provide a variety of essential and optional services for area dogs and cats. Our Leonardtown veterinarian, Dr. Lynn Fenwick, believes that the best type of medicine is preventative medicine, so of course we welcome your pet for regular wellness examinations and treatments, from vaccinations and tests to dental examinations and cleanings. If we see a problem that requires treatment, we will explain the situation and advise you on your options. If you pet requires emergency or urgent care, we can perform surgery and administer life-saving treatments 6 days a week.

Our Leonardtown vet team can also prescribe and administer treatment regimens for chronic pain or other conditions that require regular monitoring and management. Many of our patients benefit from therapy laser, a remarkable high-tech technique for easing pain and accelerating the healing process without drugs. 

Our veterinary hospital not only examines and treats pets -- it even keeps them safe and sound for you while you are away. We're delighted to offer pet boarding services that help dogs and cats stay safe, happy, and at ease as they interact with our loving personnel. It's especially reassuring to know that your pet is staying with his veterinarian, especially if he or she has any special medical needs or experiences a health situation that calls for prompt, professional attention.
