You can't train an unstable dog... it's like telling a schizophrenic person that their imagined people are not real. It's real to them and they don't share reality like we do. Sorry for anthropomorphizing hardcore on that one, but it's the best I could think of. This dog is clearly unstable, if he is going after a human that hard. He needs a bullet. (and yes, Lee.. I've done it.)
just bc the dog is untrained doesnt mean it has to be aggressive..but it is. I have seen MANY dogs untrained w/ no manners but they are not aggressive. That dog is a tickin time bomb. So many stable dogs need homes.
One dog was so afraid of everything in the world EXCEPT me, that he pissed and freaked out when he met new people, hell even people he knew since he was a pup, including my friend that is a trainer, The other one was an absolutely gorgeous bitch that was absolutely everything you would ever want in a bulldog, except for one problem; she was extremely prey driven, but she saw everything as prey, including humans other than my husband and me. We had her euthanized at about 18 months old. Do you really think these dogs were untrained, or could have been saved? Some of you people are way too quick to defend a human aggressive dog. Some dogs really are not wired right, and no, it is not always the owner that caused the problem, unless the owner is stupid enough to keep that dog alive.
