Before you start complaining about pitbulls, please go to this site and identify the Pit Bull Terrier:
http://www.pitbullsontheweb.com/petbull/findpit.htmlThen, if you identify it correctly in the first 3 tries, you can come back and complain about them some more. Many people call any stocky dog a "pitbull" when it isn't. This has caused pits to take the blame for attacks that were actually done by other breeds.
Blame the owners, not the dogs. As Cesar Millan has proved - vicious dogs are the victims of irresponsible owners. I've seen vicious labs, dobermans, dalmations, chows, poodles, and pekingese. In the right circumstances, any type of dog can be dangerous.
Check out the dog that killed a 2-month old baby in this story:
