Huge Pit Bull Terrier

Widely reported pit bull attacks in popular media have resulted in the enactment of breed-specific legislation in several jurisdictions. In some cases breed specific bans have been reversed or prohibited by state legislation.These perceptions have also led to increased premiums for liability insurance.
Breed-specific legislation has been largely found to be ineffective at reducing the number of dog attacks. Research has indicated that there is resistance by those who work in the adoption industry, applying a sharper distinction before allowing a dog to be labelled as a pit bull, as well as objections from veterinarians.
Many of the jurisdictions that restrict pit bulls apply their restriction to: (a) the modern American Pit Bull Terrier, (b) American Staffordshire Terrier, (c) Staffordshire Bull Terrier, and (d) any other dog that has the substantial physical characteristics and appearance of those breeds. Such jurisdictions include: Ontario (Canada), Miami (Florida, U.S.), Denver (Colorado, U.S.), and Malden, (Massachusetts, U.S.). However a few jurisdictions, such as Singapore and Franklin County, Ohio (U.S.), also classify the modern American Bulldog as a "pit bull-type dog". In the United Kingdom, a pit bull is an American Pit Bull Terrier.
All of the breeds share a similar history, with origins rooted from the bulldog and a variety of terriers, except for the Johnson line of American Bulldog (as opposed to the more pure Scott line), which come from the bulldog and a variety of mastiffs. The dogs called bull terriers before the development of the modern bull terrier in the early 20th century may also be called pit bulls.
