My girlfriend's pitbull Pete. He's still a puppy really, only a year and a half or two years old, I can't remember. Awesome sidekick though, he loves me.
When I was born my mom had a pitbull. She was the sweetest, gentlest dog ever.
Though she did chew a hole in the wall when my mom went out because she thought I was in my room. They found her sleeping in my crib with a huge hole in the wall.
