Are some dog breeds just too dangerous to be allowed in a city?

The Mayor of Montreal, Denis Coderre, thinks so.

His city just passed a controversial bylaw banning pit bulls and pit bull-type dogs, after a Montreal woman was mauled to death by a dog in June.

Starting Monday, people will no longer be able to own any new pit bulls or pit bull-type dogs, and those currently in the city will be required to be sterilized and wear muzzles in public. Amil Niazi, an Associate Editor at Vice.com Canada, says the move is based on fear rather than fact.

There's no evidence to prove that dog bites and attacks on humans are reduced by these kinds of bans. In Ontario, a pit bull ban has been in place since 2005 and in the city of Toronto dog bites have actually gone up in intervening years. - Amil Niazi

Niazi points out that other jurisdictions in North America are repealing their bans on pit bulls, and she says that's because breed-specific legislation has proven to be inconsequential at best, and at worst, destructive to dogs.
