In the late 1980s, an epidemic of attacks by Pit Bull type dogs, and other related breeds, led to widespread bans. In 1991, the Parliament of the United Kingdom banned the ownership of Japanese Tosa Inus, Argentine Dogos, Fila Brasilieros and Pit Bulls, with many other countries following suit soon after. Even in areas where having such dogs is legal, it can be nearly impossible for homeowners to get liability insurance if they own one of the breeds below.
Banned in Denmark, Singapore and various municipalities, the American Bulldog’s origins are in the deep south, where it was used as a farm dog. Its specialty is catching feral hogs, which can weigh several hundred pounds and wield savage tusks. When cornered, these razorbacks are nasty fighters, requiring a dog of great strength and athleticism to fight them, battling the hog into submission and holding it down until the hunter arrives. For this reason, they have a very high pain threshold. The American Bulldog can weigh from 70-120lbs., though many have been known to grow even larger.
