Who Does Depression Hurt?

...Everyone. :'(

Sis says maybe I am depressed. I say I don't know, I just don't have the energy to do much of anything lately. I lay around, especially in my old puppy crate, which Sis says is too small for me, but I say it's cozy and dark and safe. I have also been just standing around lately, not sure which way to go...too many decisions sometimes. I haven't even had much interest in eating, drinking, or going outside. Sis made me lick the water off her fingers cause I wouldn't take any from the bowl then...I did later, though. Then they practically dragged me out to the back yard, but they couldn't make me go very far. Sis asks me what's the matter, why I'm down in the dumps, but I don't really know. I heard her and Mom talking and they said they heard on the commercial for the flea medicine advatanx that it may cause depression and muscle aches-- have you pups heard anything about this? When I didn't have to take it over the winter I was a lot happier and more playful, I just started back on it and am do for another application soon-- has anyone heard of this causing depression and if I don't use that, has anyone heard of any herbal or natural remedies to keep the creepy-crawly-flying-biting-sucking-things away from me?

Luv,
