Dog like that you should kick in the teeth. On no wait, the owner is responsible, then we should kick him in the teeth.
I seriously doubt your dog is anything like that though.
Here's a story of bad owners. Someone I know was at the crag one day. There was a dog tied up there right next to the base. It bit my friend. Owner turns around and says, "Oh, he does that sometimes." F#$%ing doofus!
Dogs don't bite people, people bite people!
