A guy in our neighborhood has a super aggressive dog. It growls and barks at anything and anyone and is always trying to get off its leash whenever it’s outside. We’ve noticed that the owner is just as mean as his dog. So, sadly, they are well matched foe each other. Unfortunately, I won’t be remotely surprised if/when there’s an “incident” in their home. Whenever there’s two big dogs around, sooner or later they’re going to fight. The only question is which one is going to win.
