This is sort of a side question, but honestly, aren't all dogs therapy for depression? This is the one place, outside of a mother's love, that you could look for unconditional love. A dog to idolize you, miss you when you're out, follow you around when you're home, is up for every game you want to play, goes by your rules and cares what you think....

Hmmm. I'm depressed too, but I have cats, not dogs, and now you have me looking at that. These cats are both as crazy as I am.
