Last night I gave Murphy a bath, because he has a skin condition that I'm trying to treat. He was not happy, sitting in that bathtub, to say the least.
But there was one in the house who was even less happy, and that was Belle, who was locked out of the bathroom. She sat at that door and scratched and whined because she wanted to be included and it dawned on me that at that moment, both dogs would have gladly changed places with the other.
Of course then I'd have had Belle in the tub, all wet and sad, and Murphy...well he'd be lying contentedly downstairs in front of the stove. He's not stupid.
