Have you considered that your dog may have yeast overgrowth? One of my dogs was so itchy and stinky & after doing some reading, I discovered that she has a yeast overgrowth. The DERMagic website has a LOT of great information on the symptoms of yeast overgrowth.
My recommendation for food is VeRUS. Do a google search for VeRUS Pet Foods. If you fill out the contact form, they’ll email you back, ask some q’s, and send you free samples. I LOVE this because coupons for a few dollars off are useless if your dog doesn’t like the food. My yeasty girl is doing really well on this food (better now that I’ve stopped feeding her MilkBones – duh!).
Finally, if you’re worried about fleas, FOOD GRADE DE powder will help with them. Just dust your dog with the powder occasionally & you won’t have problems with fleas. Might work on the horses, too, if they suffer from small biting insects.
