There are three types of pit bull dogs: the American pit bull terrier, the Staffordshire bull terrier and the American Staffordshire terrier. The pit bull breed began in England as a cross between a bulldog and a terrier. Pit bulls are muscular with a broad head and sturdy build.
The American pit bull is medium sized, has a solid, well-defined body and has a short, smooth coat. This breed is friendly, enthusiastic and loyal, with a distinctive love of children. The Staffordshire pit bull is fearless but obedient when trained and makes an excellent all-purpose pet. It is quiet, stable and very affectionate. The American Staffordshire terrier is friendly but highly protective of his family. Thanks to his intelligence and athletic build, he enjoys games such as tracking.
