I worked with a guy once who had 2 pit bulls and 2 roommates. We were on a business trip when he got a call from one of the 'mates saying he had a friend over and they were playing with the dogs when the friend was bitten, had to go to the emergency room, sheriff was called, etc. Having met these dogs, I was surprised (they seemed pretty friendly at the time and I had no problems playing with them) but concerned for this guy knowing the damage they could do. So I ask him,
"How is that guy? Is he OK?"
His response,
"I dunno! What was he doing anyway? He wasn't playing with them right! You can't wrestle around them, it upsets them! "
ME: "Uhm, might be a good idea to find out if the guy still has all his limbs and such. Soooooooo, they were wrestling with the dogs? That's not smart. No wonder he was bitten."
HIM: "No, my roommates were wrestling each other! The dogs don't like that!"
ME: "So, the roommates weren't touching the dogs. . . and the dogs bit them? Aaannnddd, you're blaming the roommates for this?"
HIM: "Yeah! They should know better!"
ME: "Maybe a kennel is in order when you're on long trips, eh?"
HIM: "I guess I'll have to from now on, huh?"
Moral of the story is, the dog owner will probably blame you no matter what. In court, you'll be the cold killer Rambo-type and the dog will be pure, innocent Fluffy who would never hurt a fly unless YOU provoked him, yadda yadda.
