I've been in touch with Rottweiler rescue groups. They're not accepting dogs at the moment, and especially not dog aggressive ones.
Little by little, he's becoming more acceptive of the other dogs. When the geezer dog and the Jack are out, and when the chickens are out, he's in a crate in the garage. I want to expose him to the other animals, without risk of dismemberment of the other animals (the crate is wrapped with tie-outs to prevent him from breaking out). He's not as frenzied at the sight of the other animals as he was five days ago. Today, the Jack came into the garage while he was eating, and he didn't react at all. He'll bark at the dogs and the chickens when the enter the garage or pass by the doorway, but calmer than before.
Our next plan of attack is to muzzle him, with a prong collar, and walk him in the vicinity of another dog.
He's starting to play with a rubber bone. He's not devouring his food as if he's starving.
He's totally bonded with me. If he's loose outside, I can't go into the house, because if he sees me pass by a window he'll jump at that window.
I have to bear the expense of a vet visit. I can't expose the other dogs to him without vaccinations. It's going on a week now. If we keep him any longer, I'm going to have to get him neutered. I have hope (too great expectations, I know) that he will improve after. It would totally suck to take him for an exam and neutering and end up with the shelter taking and putting him down after all.
We just can't bring ourselves to give up on this dog, yet we don't want to endanger our child or our other animals, and I can't forget my 72 year old mother. I guess she's at risk, too.
