I thought you were talking about the singer, i see you mean pitbull as the type of dog, they do have a bad image, how do you do to not to scare people with them?
No I was not talking about the singer but he's okay. I mainly just keep my dogs to myself since I live in an apartment complex.
Ok noted, I thought about armando christian perez know as pitbull or Mr. worldwide! how do you do to keep them quiet at the apartment?
I didn't know that was Pitbull's real name, but yes they're quiet dogs already and only get loud when they sense danger.

The most popular is the Staffordshire I think, but mine is just a mixed breed of the American Pitbull and American Boxer. They're very pretty dogs.
