That sucks =( Especially since Buddy is so clearly a Pittie mix! Do your parents know there is no such thing as a brindle ACD? And there are few dogs that do have strong brindle genes, besides bully breeds?

Luckily, neither of my parents discriminate against breeds. They have their favorites of course (my Mom's being poodles and my Dad's being Collies), but they've met way too many Pit Bulls in dog sports and my friends, all of them with great temperaments.
