You know, some dogs do look a little depressed

I've heard of Doggie Downers, especially when they're on the way to the vet or the groomers. But anti-depressants for animals? What do they have to be bummed about? My Aussie could probably use a little bit of this, just so she'll quit freaking out about the refrigerator. She hates to walk past it, even if it means she can't get to her food. She's a bundle of nerves sometimes...
