Welcome to North Hill Animal Hospital in Bolton

North Hill Animal Hospital has been helping pets in the Bolton and surrounding area since 1986. The hospital, at that time, treated all types of animals from cats to cows and dogs to horses. In 1989 the practice shifted its attention to only dogs and cats with the occasional rabbit, mouse and gerbil. During the past 25 years, we have grown considerably and have had the distinct honour to help care for thousands of pets and their families.

The doctors and staff care deeply about their patients and those families attached to them. In 1989, before the move, North Hill Animal Hospital undertook the task of becoming accredited by the American Animal Hospital Association (AAHA). In Ontario, all veterinary hospitals must be accredited by the College of Veterinarians of Ontario (CVO), all practices must meet a minimum set of standards to obtain a certificate of accreditation. The AAHA standards are much more than a minimum, and by getting AAHA accreditation, we improved the level of practice and service we offer to our clients. Currently, only approximately 5% of veterinary hospitals in Ontario are accredited by AAHA.

We at North Hill care deeply about your pets well-being.

This means that somehow those dogs who were injected with the rabies vaccine were better able to fight off other diseases. So their immune system had been enhanced.

Essential Oils and Its Dangers

Are Essential Oils a Problem?

The smell of wintergreen is calming, citrus is pleasant, and eucalyptus can be soothing to achy sinuses during the cold winter months. Vaporizers, charms on bracelets and potpourri are all ways to use essential oils to impart these lovely smells to the air. We use essential oils for many things to keep us happy and healthy but we hardly ever think these fragrances can be toxic to others including cats.
