What do you do with them? Further, if it's illegal for anyone to buy them, what do you do with them?
The UK had the same problem when they banned pit bulls. Not a single dog was killed. They just disallowed people from getting new dogs, and the ones that already existed just died out of old age in their existing homes. If new dogs are found they just go to an animal shelter where they get neutered and that's it.
In some cases, like the US, unwanted (but legal) dogs go to Canada where they get new homes. Checkout YouTube for that, they all look like happy puppies.
Not a single breed-specific-legislation in the world resulted in any dogs getting killed.
What we're talking about here, is dog breed which single handedly are responsible for over 90% of fatalities and serious injuries should be neutered and not allowed to be sold to the general public. They can be in shelters, as guard dogs or used by the police or military, just not regular family homes with elderly and children who can't defend themselves.
Where did you get that gruesome idea of killing dogs from?! No one anywhere in the world has done that or even talked about it.
They have immensely powerful jaws, but are no more likely to use them than any other breed. There is an unfortunate increase in damage per instance but this again is no fault of the breed.
Can a poodle kill you? In some edge cases maybe. Can a pit bull do it? For sure.
This is correlated with lower rates of spay / neuter as well. So you have an animal that is naturally MUCH more dangerous, and then you have that correlated with folks who LIKE that they are so dangerous and the bad outcomes multiply.
Want a poodle? Here you go. Want a pit bull? You should have to prove you are going to be able to train, care, etc for them and will keep them on leash in situations where they could kill others (ie, children's playground - yes - people bring off leash pitbulls occasionally - NOT a good situation).
BTW - same rule should apply to guns. Want a .50 cal automatic machine gun? You should need some kind of extra license given the danger you now pose.
IDK where you are, but automatic guns are very hard to buy in the U.S. You may be able to buy a pre-1986 model, but the bureaucracy is exactly as onerous as you wish it to be, as is the price tag.
Or are you confusing automatic and semi-automatic guns?
Dude! Sign me up! Where is this amazing place doling them out? And yes, I’ll jump through those hoops.
I don't think 'fault' is really the point -- the question is whether they are more dangerous. The 'unfortunate increase in damage per instance' is a euphemistic way of saying that yes, they are.
"For some reason"... there is no mystery here: trashy people are drawn to the premise of dog fighting.
