The Barkeeper's Dog
A guy sits in a bar when the barkeeper starts talking about his dog, "My dog is the most vicious killing machine in the area. If I had not tied it by a huge chain, it would kill other dogs or children all the time."
And really the guy can see a doberman snarling in the corner tied by a huge chain. The guy looks up and says, "I bet you a beer that my dog that is tied up outside the pub has no problem killing your dog."
"Oh really?" answers the bar keeper, "what breed of dog do you have?"
"A long nosed, short legged, long tailed terrier," answers the guy.
"Alright," replies the bar keeper and releases his doberman. The doberman runs outside. Soon afterwards the tattered remains of the dog limps back, bleeding, all over covered with wounds, and dies at the barkeeper's feet. The bar keeper cannot understand what was going on.
"That must be a hell hound you have outside. What did you say it was?"
"A long nosed, short legged, long tailed terrier," replies the guy, "but some people call them crocodiles."
