Toronto Dangerous Dogs | 2017 List of Dangerous Dogs by Breed

In March 2017, the City of Toronto updated their by-laws on how they deem a dog to be dangerous. Instead of using breed specific legislation, the city of Toronto will decide on a case by case whether a dog is sanctioned as a Dangerous Dog. When dogs are deemed a dangerous dog they must wear a muzzle when outside their home.

In some countries and territories they will enforce a ruling based on breed specific as such they can deem certain breeds as a dangerous dog. Certain breeds like Pitbull, Rottweiller, Doberman are automatically pooled into this group as a dangerous dog not based on their behaviour simply because they are a specific breed. Such breeds are then required to wear a muzzle in public just because the breed is deemed to be dangerous.

Does the breed really matter?

Personally speaking while I am out walking a dog that people perceive to be a dangerous dog they behave very differently. People will cross the street when they see us coming, give us a wide birth on the sidewalk or simply freeze against a wall until we pass. Yet nobody has such a reaction why they see me walking with a Labrador Retriever and yet they place #3 in the list of the 2017 Dangerous Dogs in Toronto. Labrador Retrievers are consistently in the Top 5 Dog bite list across the United States and Canada.
