I know most mushers don't waste their time on a dog-aggressive dog. Is that simply because a dog-aggressive malamute is impossible to train out of that behavior? Or is it just too much work to make it worth it? I have a team of dogs, but only one is highly dog-aggressive. She was raised around other dogs, but she takes being the dominant dog very seriously, and will literally fight to the death if another dog challenges her- or if a dog she doesn't know walks into her territory. She's very submissive to humans, but will not tolerate other dogs. Can this behavior be deterred? If so- how? I've tried everything up to this point including shock collars, asserting dominance myself, and a week-long period of 24/7 supervision. She's fed separately from other dogs. Has her own tie out line. Her own dog house. She gets plenty of attention and is run often. She doesn't fight over food or even territory- she just fights, because she wants to fight. She has no reason to be so aggressive, it's just in her nature. I'd really like to find a way to train her out of it, but I'm at a loss at the moment. Any ideas?
