Anna_66 has a rottweiler, and I really do think that sweet Angus would be a bad dog. Some dobermans do turn on humans, but they should not have a bad name. Nobody knows what a dog is going to do-nobody. Dogs are predictable once in a blue moon, but sometimes they are unpredictable. I love dogs, and I would never give a specific breed a bad name. German Shepherds are usually nice dogs. I have seen some mean Rottweilers on tv, but that certainly does not mean that that breed is a bad dog through and through.
