service dog It is one of several breeds commonly known as pit bulls. In the early part of the twentieth century the breed gained social stature and was accepted by the American Kennel Club as the American Staffordshire Terrier in 1936. The name was changed to reflect difference from the Staffordshire Bull Terrier of England. Height and weight should be in proportion. The early ancestors of this breed came from England, where until the first part of the 19th century, the Bulldog was bred in England. Obo II, was born around this time. The breed was developed by landed gentry purely for the sport of hunting foxes.
Despite its name, the Staffordshire Terrier was first bred in the nineteenth century in Birmingham, West Midlands, rather than in the English county of Staffordshire where it was then later bred. A height of about 18 to 19 inches (46 to 48 cm) at shoulders for the male and 17 to 18 inches (43 to 46 cm) for the female is to be considered preferable. Bulldogs pictured as late as 1870 resemble contemporary American Staffordshire Terriers to a greater degree than present-day Bulldogs. From the 1980s, there have been changes in the role of the pet dog, such as the increased role of dogs in the emotional support of their human guardians. People and dogs have become increasingly integrated and implicated in each other's lives, to the point where pet dogs actively shape the way a family and home are experienced. There have been two major trends in the changing status of pet dogs. The American Staffordshire Terrier should give the impression of great strength for his size, a well put-together dog, muscular, but agile and graceful, keenly alive to his surroundings.
