Moody Dog?
This is for real. It's a collar studded with "mood stones" so that you can tell what mood your dog is in. Maybe it's just me, but won't this also tell you that the owner is a moron? I thought this dog mood stuff was pretty easy. If a dog snarls, isn't it in a bad mood? If it wags its tail, it's in a good mood. How many moods can a dog have? Did I miss "melancollie"? Sorry.
Anyhow, this will be helpful for those with dogs suffering from mood swings. "Oh, look. Bowser is pensive. Or maybe he's too stupid to be pensive. Maybe it's some other mood. Honey, do you know where the instruction manual is?"
