I have a confession to make: I am a pushover for dogs...even when one isn't technically mine.

Last week, our friends' dog, Copper, stayed with us while his people were on vacation. Tess, my sweet, generous, ridiculously good-natured pup, handled this like a champ. Her food? "Sure, help yourself." Her blankets? "Knock yourself out." My attention? "There's plenty of me to go around." Tess is practically a saint in a fur coat.

But then there's her special bed.

This is the doggie bed situated in front of the glass doors and close to the heater in my office. Friends, let me tell you, all saintliness goes right out the window when that prime piece of real estate is up for grabs.

Here's how it went: One dog settled into the warm spot with a blissful sigh. The other dog began to hover.
