High strung? I've known many APBTs and AmStaffs and not one was high strung... Ok, maybe ONE was, but she was a mixed breed (possibly part AmStaff) and was rescued from an abusive situation. The vast majority of the APBTs I've known were easygoing, eager to please and highly people oriented.
I've been around many many bully breeds and many other types of dog as well. The only bad bites I've had (that broke the skin more than in just a scrape of teeth) were from a cocker spaniel, a cocker spaniel/poodle/terrier mix, and a Golden Retriever. The only serious bite I've had (required stitches) was from a one-year old male Golden Retriever, and resulted in 8 puncture wounds in my hand which required 9 stitches. I still have scars on the front and back of my hand.
What bothers me the most about the news reports of "pit bull attacks" is that MANY MANY of them misidentify the type of dog involved! In many cases the media has reported on a "pit bull attack" and the dog was not even CLOSE to an American Pit Bull Terrier or American Staffordshire Terrier! I've seen one article on a "pit bull attack" where the dog's photo was included. The dog was obviously a Great Dane!
Here are a number of examples of "mistaken identity":http://www.understand-a-bull.com/Art...ty/WrongId.htm
The truth is, any dog can bite. Any large dog can do serious damage in an attack, and even small dogs can do serious damage to children and babies. There have been cases of Pomeranians and Jack Russell Terriers causing severe injury to small children. Banning or restricting ownership of one or a couple of dog breeds, or a "type" of dog which is not even well-defined (who decides what makes a "pit bull"? It's not the name of any actual breed!) is not going to significantly change the amount, frequency, or severity of dog bites.
There will always be clueless owner who don't socialize their dogs, chain up their dogs without human interaction, allow their dogs to run free, or train their dogs to be aggressive. Doing away with a dog breed is not going to change that. They will just find another type of dog instead to be the breed of choice, and maybe next it will be German Shepherds on the "banned breeds" list, or Labradors (statistically Labs are pretty high on the dog bite lists) or Border Collies. In Italy they have decided that Corgis and St. Bernards are "dangerous dogs." In Germany there are restrictions on owning dogs over 40 pounds. If "pit bulls" are banned, who's to say what breed is next?
