Thanks guys, I called Drake's vet office and they said that it might be a good idea to bring in a fecal sample. They said it could be worms or some other issues but obviously it's impossible to diagnose over the phone. For all of you who asked, we went to Alaska and Drake stayed at home with my Brother and girlfried who housesat for us. They've watched him before and we told them exactly what to feed him, so I don't know what the problem is. He's hardly a neglected dog, more like a spoiled brat. Any way, time will tell and I'm sure he'll be fine. I'll let you all know.
