My next-door neighbor has two pit bull terriers. They are a year old, and largely untrained. They live outside. They have broken THROUGH our common fence at least three times, finally stopped by hog wire lining on their side.
Say hello to Mimi and Skittles, at my back door last week.
These dogs are stereotypically sweet, gentle animals. If they were any other breed, you would think they were perfect family dogs. Wouldn't hurt a fly, come when called, etc. But they are pit bulls. Click that picture and zoom in. See how the "top" ear of the dog on the right is a little bloody-looking inside? It was almost bitten off by the dog on the left, in a fight over who got to sit on the couch.
I was sitting here minding my own business just now, and I heard the neighbordude holering like he meant it. I killed the TV and went and cracked the back door to listen. He was splitting his attention between Mimi and his daughter, who is like 4-5 years old. The dog probably outmasses the girl by 10 or 20 pounds. She had tried to take something from the dog. She did not sound greatly reassured that "it's only a scratch."
Jesus H. Christ! You can't just TELL a four year-old to leave the sweet lovable doggy alone, and to remember to never try to take something away from the dog! If a chihuahua nips at a child's hand, it stings. If a pit nips at a kid's hand it's like an iron bear trap.
Now don't get me wrong: I think it is stupid for government to ban ownership of pit bulls. Pit bulls are just dogs, after all. Big, strong dogs, but just dogs. Dogs ALL nip, especially when they are young, especially when they are untrained - pits are no exception. But they also have this little feature where, every once in a great while, they get a little crazy over not-much. Having small children and pit bulls in company is a nasty way to play russian roulette.
Just a scratch. This time.
