We just kinda gave up after he burst out of the door one morning and caught a bird before it could lift off and then went full slavering rage mode when he saw another dog. We could have possibly introduced him to other animals but felt like it would stress him out, add danger to the other animals, and we had the space to let him be a dog without it becoming an issue. Most of his interactions with other animals was the local coyote pack coming to see if he was easy pickings yet. The last 2-3 years of his life I would follow him on his nighttime bathroom breaks with a bat ready to help my old man in his last battle. Luckily it never came to that and he died peacefully in his sleep on my lap.
