I have a 8 month old pit. He was put outside yesterday around 12 pm on a tie out leash. When I went to get him inside he was gone. I searched the woods around my house for hours. After about 7 hours of him being missing he showed up at my back door. Im not sure whether he was taken or just got loose himself. But he is really weak, and lazily acting. He will NOT eat and he barely drinks. I don't have the money right now to go to a vet. Any suggestions?
