What are your feeding now? And what have you tried? Soy tends to cause itchy flakeing skin, so I have heard. I would look into a raw diet. I am starting my little sheltie on a raw diet tonight. I've spent alot of time researching it and it is supposed to really be great. One thing the raw diet can help is itchy flakey skin. I wouldn't recommend the BARF diet though. Check out this website www.rawlearning.com and check out others like it. I hope you found this interesting, and I hope I helped a bit.
