So sorry this happened.
I've met some Pits and dogs that look like pits and some of them were the dopiest, sweetest animals you could ever know. But that's just not all of them, unfortunately.
That said, I'm also very grateful that we're not talking about the mauling of that 10 year old or your mother in law.
I was jumped by a German Shepherd when I was a kid and I never really got over my fear of really big dogs. Don't tend to like small dogs either, but unless the big dog's smiling, I tend to get scared pretty quick.
Hope the kid's okay. Even a non-biting show of aggression is enough to really mess a kid up.
Sorry for ya, bud. He looks like a real sweetheart with a great smile.
