And your missing the point on the Dangers of Pittbulls, its not Jaw strength thats dangerous. Jaw strength (unless you are very weak such a child or elderly or a very petite man or woman) is not a big issue, it may hospitalize you, but it won't kill you.
Pure body muscle. A pitbull is all muscle. Even with a Muzzle on a Pitbull could easily kill someone with raw muscle power.
They are no more muscular than Dobies or Rotties or Bullmastiffs. And that really varies from animal to animal. I've seen more fat couch potato pits than I care to admit. I don't see how a pit is going to kill you with his raw muscle power. The vast majority of fatalities are in children because of their size. Pits tend to snap at whatever's close, which is why usually most adults get bitten on the arm or leg.
There is no reason to own an animal that deadly no matter how cutesy you think it is. Bears are cute and intelligent too, and far more docile. Right up until it spooks and kills half a dozen people.
A dog is not a bear. I'm so over the "a dog is just like a bear, elephant, jaguar, mountain lion, airplane, pitchfork, gardening hose, stingray, shark"... whatever comparison. A dog is a dog.
None of our pit or pit mixes have ever been dangerous. The most dangerous animal I've ever owned is my current dog. I don't need to euthanize him though, I keep him out of situations where he could bite. It isn't that hard to do.
Quite frankly, domestication only matters in terms of suitability if the animal has been bred to BE passive. Fighting dogs have been bred to be specifically aggressive.
Fighting dogs were bred to be ANIMAL aggressive and not human. If you don't understand this difference, then you don't know about dogs.
Animal aggression is bred into several breeds. My dog is a form of rat terrier. He's about 15 lbs and was bred to chase down rats, catch them and shake them to death. He does that exact motion with his toys even because it's his instinct. He will naturally go after anything small that moves fast and try to kill it. That's not the same as being trained to kill humans. He won't hunt a human down and try to shake it.
Dogs used in dog fighting were bred to be aggressive towards other dogs. Because of their power, dogs that bit humans were culled. The dog owner had to trust his own dog wouldn't turn on him when he went into the pit in the middle of a fight and pulled his dog out. The dog also had to be stable enough to allow his opponent's owner to come over and inspect and bathe him (to make sure no cheating was going on). Few breeds are capable of this btw. I know my small dog would bite the crap out of me if he was in a frenzy attacking something and I reached in. And there is no way in hell my dog would allow a stranger to touch him, let alone bathe him.
No matter how cutesy you think Fighting Breed dogs are, they will do what they were bred to do. Even you can train them not to (and you can, same as you can with a bear) they are too dangerous if you don't train them properly.
They were bred to kill other dogs, not people.
In terms of power, a German Shephard and even a rottweiler (though they are pretty damn strong) is nowhere near the power of a pitbull, which can kill or seriously injure someone with a muzzle still on.
Bull. Pits range in size from about 40lbs to about 120lbs. Some are powerful, some aren't. There is no evidence to support your claim that they are so much more powerful than dogs of similar size of another breed.
Your logic that it is somehow wrong to ban one type of animal if you allow another type is absurd. You want an inquisitive dog? there are many, you don't need one that can run through an average hollow house door (and I've seen it happen when someone opened up its treat bag just as someone else was slamming the door, although it was pretty damn funny)
There are a lot of breeds out there that make suitable pets for people. One suitable breed for me is an AmStaff. It isn't for everybody. Even the most devoted to the breed would stress that. I love them, I've always had good experiences with them and don't see any other breed that matches their good qualities. I like bullmastiffs, but they aren't playful enough. I like boxers, but they have too many health problems and don't do well in small living spaces. I like retired greyhounds, but they aren't smart. I like Bouviers and St Bernards, but they are too furry. I like schnauzers but they are too mouthy. I like Rotties, but think they are too scary looking. I like Great Danes, but they are unhealthy (same for English Bulldogs, beautiful temperaments and completely unsound physically). I think Shepherds are probably good dogs, but I'm personally uncomfortable around them. Same goes for Huskies and Akitas, they just freak me out for no particular reason. I've had a Chihuahua, but they are too sensitive to everything. I like pugs, but they're too sensitive to the heat and shed a lot. I dislike Labs, Spaniels and Retrievers in general, they've been so overbred. Dalmations are too hyper....
It isn't like I'm someone who is completely unknowledgeable about dogs and says "I want a scary looking killing machine!". I realize those people are out there, but some of us who own these dogs own them because they are truly great animals. Ours have all proven to be excellent pets, many of them live their lives without neighbours even knowing they're pits or pit mixes. I've gotten a lot of "Oh, he's so cute, is he a boxer?" type comments. Call them AmStaffs and no one minds their presence, people love them and want to play with them. Say Pitbull and suddenly the same dog becomes a vicious beast to be feared. I actually prefer a smaller, lighter, blond coloured pit if possible simply because people don't react to them the same way as they do the heavier, darker ones.
