I'd definitely take him off of RC. Meeko was one that from his breeder and use to scratch a lot! I switched him to a grain-free food and he hasn't scratched since. The problem is most dogs are allergic to corn and grains and RC has both in their food. Some good grain-free foods that are popular here are canidae, merrick, wellness core, and innova evo. There's a website (
Dog Food Analysis - Reviews of kibble) that rates dog food. I try to stick with 5 or 6 star foods. It depends on what you have available in your area. Good luck!
