There are two shows on cable(?) television about Pit Bulls. One is new, called the Pit Boss. The other, I can't remember the name but it's about a rescue outfit in ?Nevada? run by a woman who takes on Parolees trying to make a better life. Both shows are examples of how most of these dogs are very gentle but some that aren't because of their background. The Pit Boss is a little person who handles dogs that he's not met before; he gets a call about a stray, and he rescues it.
About 8 years ago, I lived in a city know for it's macho types and their propensity to raise dogs for fighting. Evil evil practice!! I will never forgive Vick! People are the monsters, not the dogs.
Earlier today I went to the bank, parked next to a car with an enormous yellow lab sitting in the back seat, nose out the window. I LOVE labs, was raised with them. As gently as I know these dogs can be, I wasn't about to put my hand in the window to pat him. After all, he's probably guarding his territory and doesn't know me. It's a matter of how they're raised, their socialization to people, and knowing the basics of dog behavior. There are as many good stories as bad for any breed of dog. Get to know the puppy!
Sorry for the soapbox. Guess I haven't lived away from that city long enough.
