The APBT is not recognized by the American Kennel Club, unlike the closely related breeds the American Staffordshire Terrier and Staffordshire Bull Terrier (commonly also refered to as pit bulls). It is, however, recognized by the United Kennel Club.

"The essential characteristics of the American Pit Bull Terrier are strength, confidence, and zest for life. This breed is eager to please and brimming over with enthusiasm. APBTs make excellent family companions and have always been noted for their love of children. Because most APBTs exhibit some level of dog aggression and because of its powerful physique, the APBT requires an owner who will carefully socialize and obedience train the dog. The breed's natural agility makes it one of the most capable canine climbers so good fencing is a must for this breed. The APBT is not the best choice for a guard dog since they are extremely friendly, even with strangers. Aggressive behavior toward humans is uncharacteristic of the breed and highly undesirable. This breed does very well in performance events because of its high level of intelligence and its willingness to work. "

I've had quite a bit of experience with pit bulls (and the dogs commonly mistaken as pit bulls). I think it all comes down to good leadership. All dogs have the ability to be agressive or not agressive, it is all in the leadership it is given. I have fostered many bull-type dogs and have never had a human or dog agressive one.

I don't really think the test is misleading at all. Although some of the breeds are related, they are not "pit bulls". It would be the same as giving a pick the lab test and including newfoundlands, chessies, and flatcoated retrievers.

Just My opinion though.
