Our recently-acquired dog has been having some major behavior problems and showing some aggression that worries us because we also have a 6-month old child. We've been taking the dog to training classes but so far it hasn't been fruitful. Should we give him back? (TLDR details inside)
My wife and I adopted Flip, an Australian shepherd mix, off Craigslist at the end of March. (At least, we were told that was his breed,
here's his picture if anyone cares to weigh in.) Our last dog had just died after a battle with lymphoma. We really, really missed him and found our house empty without a dog, so two weeks later we got Flip. I guess you could say he was a rebound.
We started having problems with him immediately. The biggest concern was barking ... he's 5 years old and didn't prove to be easy to train out of the habit, unlike our last dog. He clearly considers the house his domain and barks when anything gets within a 200 foot radius. He'll acknowledge me when I correct him but if the stimulus is still out there he'll then continue to bark. That's not a huge problem, though ... I'm a dog person and I love playing with him in the backyard, like his companionship and find his personality really amusing.
The bigger problem is his aggression. He's one of those dogs that whenever he sees another dog he instantly goes all aggro on it. He inspires aggression in other dogs, too. Snarling, rip-your-throat-out aggression. We quickly trained Flip out of nipping habits towards us when we got him (the cattle-dog traits of nipping at your hand or hip if you're going an unexpected direction, etc), but if he's running after another dog and I correct him with the choke collar, he will transfer the aggression and attempt to snap at me if I'm in his way. I immediately discipline him when this happens (pull him down by the scruff of the neck and pin him until he stops fighting it) but this trait worries me.
Last night at dog training was awful. He barked at the other dogs the entire hour, he refused to sit down with his back to other dogs, and when the instructor took him to demonstrate a particular heeling technique, he nipped at the instructor's hands and crotch as he was led around. The instructor has suggested we get a pinch collar, which we will certainly do, but my wife and I are worried that these behaviors are going to end up with our son being bitten once he's old enough to start annoying the dog. We never leave the two alone together but we don't want to keep Flip if there's not a good chance that we can train this behavior out of him.
What would you suggest?
