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.

When swimming can be dangerous: Blue-Green Algae

Cyanobacteria (also known as blue-green algae) can bloom in lakes, streams and ponds, most often during periods of hot weather in mid- to late-summer months but can be present in lower concentrations throughout the year. The algae take on the appearance of blue or green paint on the surface of the water. These algae can produce microcystins and anatoxins which are toxins that affect the liver and nervous system respectively. Even a very small amount can be deadly!

Brain Development

Puppies and kittens are, I must admit, my favorite part of practice. Seeing these cute little bundles of energy for the first time always makes me smile.  I am excited knowing they will have good homes and be cared for very well. One of the many things which fascinates me about these little ones is how fast they grow in size and how their behaviour matures with age. Every puppy and kitten is born with almost a full complement of neurons in the brain but the brain itself continues to grow during the first year of life. This growth is caused by the formation of interneurons or connections between neurons or brain cells. These connections form whenever puppies and kittens learn something so, in essence, the more they learn the more connections there are and bigger their brains become, to a certain limit. Research shows developing brains form connections at a rate of 50,000 per second (yes that many) so this suggests learning is happening at a very rapid rate.
