It's our Pit named Theo at about 6 months, when he was about half the size he is now ... bestest, sweetest dawg evah! This boy wouldn't hurt a fly, we have him around my g/f's nieces and nephews that are like 3-5 y.o., and he's so gentle with them. When anyone raises their voice in the house, he runs to the corner and starts shaking. He's a total baby. Pits get a totally bad rap ... it's all how you raise 'em.
Oh, and Pits and American Bulldogs are clearly related, eh?
