You never know when dog might want to bite, breed sometimes matters and other times doesn’t at all. I know somebody that got bit in the dick by a Chihuahua as a kid. My parents used to have an evil Yorkie, rip. There was a a Rottweiler named Ursula in my neighborhood growing up that used to scare the shit out of me daily as I had to walk by it on the way home from the school bus.
