[MENTION=33360]PeanutnCookie[/MENTION] I'm not to familiar with dog foods anymore, but maybe you can convince your parents to buy a can or two and see how he takes it. If he is by far more interested in it than the kibble, I would kind of lean towards teeth problems. He can have them, even at a young age. My cat had done it since he was a kitten. It would also help to rule out whether or not he might have a parasite like someone else mentioned. His appetite would be gone whether or not you gave him something he liked. With worms, animals will eat and eat but not put on any weight, so I kind of doubt it's that. If it turns out that he likes the wet food, a way you can save money on it is by mixing kibble in with half a can of wet and let it sit for about ten minutes before serving it to him. Then you can save the rest of the can, wrapped up in the fridge. But I would still recommend taking him to the vet. If a dog isn't eating and you're offering him a wide variety, I would kind of assume there must be something wrong. Especially as he doesn't seem to get hungry enough to gulp down a whole bowl of food after awhile. Even if he does go for the wet, you should still check it out to see if it is his teeth, the vet would probably be able to help you there.
