Lazy chihuahua

I have a dog so lazy that if she rolls off the pillow upon which she lays 23 hours per day, she will lay on the floor where she falls waiting for someone to pick her up and put her back on the pillow.

In this photo, she is yawning, bored from the long wait for someone to pick her up again. El Jefe has spoiled her rotten. She truly believes that she is daddy's little girl and shouldn't be subject to all the stuff all the other (boy) dogs are.

Where did that expression "work like a dog" come from?
