This dog is unbelievable not good I am thinking.

This is frightening. I sincerely hope this breed doesn't become popular. Born-in aggression can only mean disaster fro the dog and anyone unlucky enough to cross his path.

You wouldn't have a chance if this guy knocked you down. Watch, this dog will be the one some of the really bad pit bull owners will need in the hood.
