Everything @The Blackangel said is true. Pit Bulls are cuddly, affectionate, big babies. They get their bad rap from the dog fighting community and from the news. The new LOVES to sensationalize bad stories, which include dog bites. If you look carefully at news articles that talk about someone or someone's pet being attacked you will notice that if the breed of dog is not a Pit Bull then news will NOT mention the dog breed. If it is was a Pit Bull then the news jumps all over it. You also have to take in account reports of dog bites. If you get bit by a small dog and hardly an damage was done which does not require going to the doctor, it will not be reported. If a big dog bites you, you are more likely to see a doctor and it will be reported. I had a female Chihuahua who loved me and only tolerated other. She has bitten BOTH my mom once and my wife twice. As for my wife's Pit Bull she has NEVER bitten everyone. In fact when my wife's Pit Bull interacts with other people she loves to go up to them to get petted. Also at home we have another Chihuahua (male) who thinks he owns her (he loves her to death) and has on many occasions chased her around. He will also growl at her if he wants her spot, does not want her eating with him at the same time as him, or if he does not want her near him. She always demurs to him. She will just get up and go somewhere else. If you need one more example we recently got two new puppies, another Chihuahua and an English Bulldog. Our male chihuahua hates her, the other puppy loves to play with her, and the Pit Bull is not fond of her but tolerates her and occasionally plays with her. The male chihuahua growls and stands his ground if the Bulldog comes anywhere near him. If the Bull Dog comes near our Pit and she does not feel like playing she will literally get up and walk away. Many Many times when the Bulldog jumps up on the couch and the Pit is laying on it, the pit will jump down and lay on the floor yielding the couch to the Bulldog. Our Pit is a big pushover.
Pit Bulls: Why the Bad (and Inaccurate) Reputation? (foundanimals.org)
This article is a good one that debunks the myth of PIt Bulls getting a bad rap. To point out a few things that they talk about:
1. "Other mischaracterized canines include rescue dogs like St. Bernards and German Shepherds."
2. Pet experts staunchly opposed to policies that discriminate based on breed. The following groups agree:
Humane Society of the United States
American Bar Association
American Kennel Club
American Veterinary Medical Association
American Veterinary Society of Animal Behavior
Centers for Disease Control and Prevention
National Animal Control Association
National Canine Research Council
US Department of Housing and Urban Development
The Obama Administration
