For any canine, especially one with wolf heritage, a raw meat/bones/organ diet is ideal. You must take the time to learn how to feed this way, but since these are carnivores, it's the best diet you can feed. If he is having problems holding weight, adding cuts that are more fatty will help too. I would also have him checked for internal parasites (worms) and maybe bloodwork if that comes back negative.
If you are feeding a dry dog food, especially a lower quality one, that also will make it hard for him to maintain his weight.
