You can also check out enrolling him in a man's best friend type of class. My ex husband's family did that, and, they were all better off for it, especially the dog (a sheltie). They have classes where you leave the dog at the school for x amount of weeks to be with the trainer. That could help Ozzy a lot, and, it would also give you some time to yourself to figure out if not having him in your life is really what's necessary. I'm glad to hear you are reconsidering. I think Ozzy will thank you for it. But, maybe something like that could be an idea, too. Then, even if you have to rehome him, he'd be a more obedient dog! Either way, keep us posted....
