Hello I just recently bough a black lab mix puppy from the pound and he was found as a stray. When we first got him he was fine and happy he played, ate his food, and took walks with us. Lately hes been lethargic, not eating, or wanting to go on his walks.Also he will whine while he chews on his toys, he has a couple of his shots, and hes only about 12 weeks. The thing thats werid is when we go to my fiances parents house he will eat the food they give to their dog and he will run around and play. But as soon as we get him home he returns to this werid behavior. Any Ideas?
