Take the pit bull identification test

Accurate identification of pit bulls can be difficult.  Breeds of dog other than the pit bull are often involved in dog attacks, and are occasionally mistakenly identified  as a “pit bull”.

If one examines the photographs below, it becomes clear how this could readily  be done. Many breeds have similar physical appearance to that o a pit bull type dog, both in shape, size and facial features.  This is particularly true of mastiff type dogs.

Below are photographs of 16 different breeds.  The photographs below were checked carefully for reliability, and posted with near certainty that the image represents  the breed to which the dog is identified.  Scroll to the bottom of the page to reveal the dog’s identity.
