"The American Staffordshire Terrier, known to their fans as AmStaffs, are smart, confident, good-natured companions. Their courage is proverbial. A responsibly bred, well-socialized AmStaff is a loyal, trustworthy friend to the end. AmStaffs are stocky, muscular bull-type terriers standing 17 to 19 inches at the shoulder. The head is broad, the jaws well defined, the cheekbones pronounced, and the dark, round eyes are set wide apart. AmStaff movement is agile and graceful, with a springy gait that advertises the breed's innate confidence. The stiff, glossy coat comes in many colors and patterns. AmStaffers describe their dogs as keenly aware of their surroundings, game for anything, and lovable 'personality dogs' around the house. AmStaffs like mental and physical challenges. They are highly trainable, as their many forays into showbiz suggest. When acquiring an AmStaff, there's only one way to go: Do your homework and find a responsible AKC breeder."
"Years ago in Great Britain, several dog breeds were created to excel in blood sports. They were expected to fight one another, or they were turned loose in packs against a staked bear or bull, with spectators betting on the grisly outcome. Such revolting pastimes have long since been outlawed. These sad spectacles did, however, leave us a happy legacy: Several of today's most loved breeds' the Bulldog, the Bull Terrier, and the American Staffordshire Terrier among them' got their start as fighting and baiting dogs of the 18th and 19th centuries. When it comes to the bull-type terrier breeds, all can agree that the common component in their makeup was the Bulldog. (Note that the Bulldog of 200 years ago was a vastly different, more ferocious creature than the lovable 'sourmugs' of today.) Argument begins when breed experts try to nail down which preexisting terrier breeds reside in the AmStaff's genetic background. Some suggest that such extinct breeds as the White English Terrier and Black-and-Tan Terrier were part of the genetic mix that led to the creation of the Staffordshire Terrier, forerunner of the AmStaff. Whatever the AmStaff's true genetic composition might be, we are certain that working-class Brits with an interest in blood sports combined the stocky build and punishing jaws of old-style Bulldogs with the innate courage and 'gameness' of terriers to create bull-type terrier breeds. By the mid-1800s, Staffordshire Terriers had arrived in America. U.S. breeders developed a Staffordshire Terrier that was larger than the English version. Eventually, the AKC recognized the two types as separate breeds: the Staffordshire Bull Terrier and the American Staffordshire Terrier. The well-bred AmStaff of today is a more mellow fellow than his pit-fighting ancestors and has long been a great American favorite. This is suggested by the breed's many sightings in our popular culture: In 1903, an AmStaff named Bud was along for the ride on America's first cross-country auto trip (the subject of the Ken Burns documentary 'Horatio's Drive'); Petey, in the old 'Our Gang' film comedies of the 1930s, was an AmStaff, as is Tige, the dog in the Buster Brown Shoes logo; and America's most decorated American war dog was an AmStaff named Sgt. Stubby, a K-9 of World War I who counted three U.S. presidents among his admirers."
