If I were you I'd probably try a raw diet at this point. Raw meat, bones and organs, and that's it. No oatmeal, potatoes nothing. Portion controlled (of course) so you can monitor and manage the body weight. It will encourage fat loss and encourage lean muscle mass. Supplement with fish oil (omegas) for healthy skin/coat.
