A couple of dogs in Maryland take the title of "man's best friend" very seriously.
An 87-year-old man was playing outside with his dogs when he suddenly became stuck in knee-deep mud and couldn't get out. His dogs, knowing something was wrong, jumped into action.
The dogs ran over to a man passing by on a bicycle and alerted him to their muddy owner.
The man called the fire department and they were able to pull the man out. Luckily he wasn't injured. He now also knows that he can always count on his dogs to protect him.
