I would love to have vets stop selling SD "regular"--I don't mind selling i/d for short-term gut problems, but by selling normal SD they give exactly the impression you've gotten, which is that it's the best food. It is FAR from the best.<br><br>
The very best you can do for him is a raw diet--I don't know where you are in OK, but look for "raw diet dog oklahoma" and see if you can find a distributor of any of the brands near you. You want a frozen diet that is raw and has no grains.<br><br>
If you cannot find a frozen raw distributor and you don't want to make it yourself, I would switch him to one of the grain-free kibbles. Brands include Wellness CORE, Innova EVO, Nature's Variety Prairie, Orijen, etc.<br><br>
Third choice would be a super-premium kibble with grains. Back to Basics, Solid Gold, Canidae, Timberwolf Organics, etc. If you use a kibble with grains, watch his skin carefully and consider switching foods to different grain sources (from corn to rice, from rice to oats, etc.) to get the best results. You should be supplementing kibble with salmon oil or fish body oils.<br><br>
One of the best easily available shampoos for skin issues is EQyss Micro-Tek; look for it at horse feed stores. You should also get the Micro-Tek spray. Rinse ridiculously thoroughly, towel dry, and then part the skin and spray with Micro-Tek all over the body. You can spray his skin every day (don't need to wash first) if you need to.
