Dogs are carnivores. They are all bred to attack and kill. It's how they eat. They also tend to be territorial. Burst through the front door of their territory at odd hours, and they will act aggressively. Maybe even bark. They sometimes, shed too. It's what dogs do.
Cops that don't recognize that are too damn dumb to be cops. I don't mind cops defending themselves. I don't mind any person defending themself from what they perceive to be a legitimate threat...but any person who perceives a corgi as a legitimate threat has some serious issues.
You ‘forgot’ to mention it was a pit-bull. Funny how many times that has happened on this thread.
