4-26-20 Ozzie comes into rescue, as another owner surrender, and sounds like he has been bounced around previously.
Ozzie comes her without vetting, and was surrendered due to fighting with the other two (making it three) intact males in the home.
The owner surrender also stated that when they disciplined him, he was defensive to that correction.
As well as the biting while the dogs were fighting. The owner surrender said that the defensive biting had stopped after they stopped doing it to him.
