Growing up, one of the sweetest dogs I knew was a Pit Bull named Oliver. So I was pleased to find via Yahoo a photographic reminder that the Pit Bull was not always the feared dog it is these days. Apparently in the late 19th and early 20th Century, the Pit Bull was even known as "The Nanny Dog" because of its steadfastness and reliability.
This is a case where photographic evidence presents the most convincing proof. And the further you dig, the more supporting data you find. So here just a few images in defense of the breed.
