I thought that Pete was an American Bulldog.
There were a number of Petes. The most famous was registered as an American Staffordshire Terrier while others were UKC registered American Pit Bull Terriers. In either case both would fall under most proposed or active breed specific legislation...as would the American Bulldog, and Helen Keller's dogs, and Teddy Roosevelt's dogs and George S. Patton's Willy.
