Our dobe rescue "Rusty the amazing felon " is hypothyridic so it is the opposite problem, we have trouble keeping his weight up. He is on meds 1x a day and we add some extra fat to his food. His vet wanted to see 4 pounds this month and he is doing really well. We do feed him Raw as when we adopted him we were aware of his issue and felt more natural maybe be easier to help him balance his body. So far it is amazing for him. That isn't to say it will work each time but his vet is open to the raw diet and glad to help us tweak it for his needs, he is also vWB + at the 7% range. And he thinks he is a toy poodle
