Its a Doggy Dog World

I'm sure you've heard of the phrase "Work Like a Dog"

Well, I heard that phrase recently, and it got me thinking. How can "work like a dog" mean work very hard, when most of the dogs just laze around the whole day and pick up newspapers every morning (well, those dogs they show on TV anyways).

Not to mention dogs like Paris Hilton's Chihuahua which is more pampered than regular human beings.

Hmm

I too want to "Work Like a Dog"!
