Dogs always seem ready to come to man's rescue, so it's only fair that we should return the favor when the opportunity arises. Still, loyalty has its limits.

Floridian Greg LeNoir recently showed his loyalty has no bounds by punching a shark to get the fish to release his 14-pound rat terrier, Jake. The canine was swimming in a marina in the Florida Keys when he was brutally seized and dragged underwater. LeNoir's quick response and subsequent knuckle sandwich apparently caused the shark to release his intended prey.

"I clenched my fists and dove straight in with all my strength, like a battering ram," said LeNoir. "I hit the back of the shark's neck. It was like hitting concrete."

LeNoir thinks the creature was either a bull shark or a lemon shark, and even though Jake survived, he did suffer a few abdominal punctures. "The shark put almost all of Jake's body in his mouth, except for his head and three of his legs," said LeNoir.
