Like the government of Ontario people?
Dogs were bred for certain purposes. Some are bred to look like faceless gargoyles ei the Pug, French Bulldog, English Bulldog and the Pekingese. I'm opposed to these dogs because they were bred for their look, not for their health. It's genetic mutation.
Some were bred for assisting in hunting like flushing out birds or "retrieving" birds. These are popular dogs but not dogs that should live in apartments or cities, they need constant exercise. You need to keep dogs active or they'll get bored and become troublesome. Bird Dogs like Spaniels are alright because they're relatively small and can achieve decent exercise by decent walking.
Some were bred for herding cattle and sheep. There's a trend for people buying a boarder collies because it's determined to be the smartest breed or an Aussie Sheppeard (I guess cuz they have cool blue eyes). People who buy these dogs in an urban environment are also knobs. You can see these dogs in dog parks. They're genetically disposed to herd everything. They also require a great deal of exercise.
And some are bred for functions like fighting, guarding or killing large game. Now here's where it gets complicated and contentious. I'll concede that good responsible dog owners can breed and raise these "fighting" breeds to be great dogs. But just like people who feel they need to own an assault rifle, people buy these dogs not because they're good companions, they buy them precisely because of their heritage as violent dogs. Is it manly for an adult male to own a Yorkie or a Pug? How bout a Rottie or a Pit Bull?
Do no it's not a problem with the dog as much as the owner, but you have to ask what type of person wants a dog that has violence bred into them.
