What are main facts about pittbull classifacation?

Answer 1

"Pitbull" is not a breed of dog. The word is a loosely-applied, colloquial term used to refer to several breeds of dogs originally bred for baiting bulls in a pit; the term was later applied to dogs bred for fighting other dogs. The word pitbull is casually applied to the following breeds, or crosses of the following breeds: Straffordshire terrier, English bull terrier, American Staffordshire terrier, American bulldog, English bulldog, white English bulldog, and other dogs with similar, stocky builds which may or may not have actually been bred for fighting. Although the term "pitbull" applies to many dogs that are now classified as terriers, all of these dogs were originally bred down from mastiffs.
