While I don't hate the breed, I have had some really bad experiences with them, and everytime something bad happens around here, it's always a pit bull behind it. But then again, I live an hour and a half away from Los Angeles, and it's "cool" to have a pit bull to show off.
My neighbor breeds them, and he used to allow them to roam the streets, until his German shepard got hit by a car. The pits are always nasty mean dogs, while the german shephard didn't show aggression or threaten people. I witnessed the male pit kill a cat, and then carry his trophy home.
A few years back, a 10 year old boy named Cash Carsen (who lived about 10 minutes from my house) was mauled to death by a pit bull and a pit mix. They attacked him right infront of his best friend, who was fortunate enough to jump into a tree for safety, or he probably would have been killed as well. Both boys happened to be walking past the dogs yard, when the dogs attacked.
In 1989, my neighbor's horse Cody was attacked by two pit bulls when Mr Rivera was riding him. Cody threw Mr Rivera off, and took the blunt of their trauma. His stomach and neck was ripped open and he was lucky enough that time, money and stitches was able to heal him. Then in the early 90's, another neighbor was threatened by two pit bulls that had ventured into his yard. Bad decision on their part, as he is a sheriff, and shot them both.
I read the article that says that Pit Bulls have the same jaws as every other breed. I'm sorry but I strongly disagree, as will everyone who has personally been around the breed. My dog, is 1/5th pit bull, but he resembles a terrier/poodle mix. When he was a year old, we took him to get his shots, and the guy who was giving the shots asked us what breed of dog he was. We told him that he was a mutt, because we didn't want to own up to having a pit mix. He took one look at my dog and said "He has pit in him, you can tell by his jaw." He hadn't spent more than 2 minutes with him, and yet he knew that he had the pit. And I know that my vet HATES when people bring in Pit Bulls to his office. They are a liability waiting to happen, as he puts it.
I do believe that a lot of pit bulls are very loving, loyal dogs. However, I don't think I could ever be able to "chance" having one around a child or my pets. Even after years of being good, it only takes one time for them to snap, for someone or something to die. I would much rather have someone I love attacked by a dog that bites numberous times, than a dog that grabs ahold, and shakes his victim violently.
