So what set it off? Her face being close to its face? It's not like she jumped at it. She'd been petting it. She was doing like we all do with big dogs. We want to let them and hug them. But I'll be damned if it isn't always a pit that just isn't wired like other dogs and they're hard to figure out. If the answer is to just always be weary and distant, then they shouldn't be inside. They should just be security systems.
