Does your dog bite?

A man walks into a pub and sits down next to a man with a dog at his feet. "Does your dog bite?" he asks the man.

"No." comes the reply

A few minutes later the man leans down and reaches out to stroke the dog at the other man's feet.

The dog snaps at him and takes a huge chunk out of his hand.

Reeling back, the victim stares angrily at the other man who sits quietly drinking his pint apparently unruffled by the whole incident

"I thought you said your dog didn't bite!" the injured man says,indignantly.

The other man turns and looks at the dog, then looks back at the injured man.

"Yep" he answers......

"But that's not my dog."
