Never met a puppy I didn't like, and rarely have met a dog I didn't like, or more precisely, that didn't like me!
One of the coolest stories I heard about today. A British naval officer suffered debilitating brain injuries during Desert Storm, which caused him to become very withdrawn. It took a yellow lab to break him out of his shell. The dog then became his companion until he was able to reconnect with the outside world enough to remarry his wife and bond again with his children. That a dog can do that is pretty strong indication of how special that connection between man and dog can truly be.
