response: I don;t know how long they have been bred but a lot of mixes breed dogs are often called pit bulls
history: i have two dogs , one pitbull and old english bulldog. Their names are marco and polo. Interesting, which dog is the pit bull? Marco is the pit bull. Do you know how long people have been breeding them? I heard they can be aggressive but mine is lazy.
knowledge: While mixed breed dogs are often labeled as ''pit bulls'' if they have certain physical characteristics such as a square shaped head or bulky body type, visual identification of mixed breed dogs is not recommended by the scholarly community.
