The three "main" breeds of dog known as "pit bulls" are Staffordshire Bull terriers (SBTs), American Pit bull Terriers (APBTs), and American Staffordshire Terriers (ASTs). These are the ones [i]always[/i] included in BSL. Sometimes the description or "pit bulls" in BSL also includes Bull Terriers (BTs) both miniature and normal size, and American Bulldogs (ABs). The differences between them aren't really that big, so it can sometimes be hard to tell what's what (one reason why BSL doesn't work). From what I understand and have read, the three main pit bull breeds (SBTs, ASTs, and APBTs) started out as one "breed", known simply as "bulldogs", because they were used to work bulls and other stock. They proved to be good at these jobs, so people began using them in bloodsports (bullbaiting, bearbaiting, dogfighting, etc). As people came to America, they brought over the dogs which would be the foundation for all APBTs and ASTs. Over time, bullbaiting and bearbaiting were outlawed in many places, so dogfighting took over as the prevalant "sport". Eventually dogfighting was made illegal, too, and that's how it is today...
The "bulldogs" in England and countries near there, no longer used for fighting/combat became the SBTs that exist today. Short, stocky dogs, but still very powerful. They are the dogs known as "nanny dogs" in England for their excellent reputation with children. Most of them still have the "bulldog" attitude, they're just a "scaled down version" :wink: . They are usually around 15" at the shoulder, and are supposed to be 40lbs or under.
As for the American "bulldogs", they were known by several names, including "pit bulldogs" and "pit bull terriers". They were turned down for breed registration by some registries because of the word "pit" in their name. The UKC was the first kennel to recognize the APBT as a breed, in the late 1800s. Then in the 1930s, the AKC recognized ASTs as a breed, so many APBT owners also registered their APBTs as ASTs. At that time, the two breeds, APBTs and ASTs were identical. Over time some differences have developed between them, ie: in ASTs, a red nose is considered a fault. APBTs are generally considered the "performance pitbulls", and ASTs are considered the "show pitbulls", but these are just generalities, and both breeds are "athletic". ASTs are usually about 18" tall, and their weight should be proportional to their height, but most are 30-70 lbs. Red (dudley) noses are a fault in ASTs, and are uncommon, but so appear occasionally.
APBTs are usually divided into two "groups", the "show APBTs", and the "performance APBTs"(used for weight pull, schutzhund, hog catching, sometimes illegal dogfighting)"Show APBTs" are similar to ASTs in appearance. "Performance APBTs" look more athletic, and are often "ugly" to some people, but they are bred for their ability to work, not for their appearance. There is a wide variety in appearances in performance APBTs, some are smaller, some are larger, some don't even look like APBTs. All APBTs are usually in the 20-70 lb range, with dogs occasionally being more/less than those weights. There isn't really a set height, most are in the 18-21" range, but some are taller/shorter. Red noses are allowed in APBTs.
Sorry this got so long :o , but I hope it helped some, or at least didn't confuse anyone anymore than they were :lol:
