Hi Jennifer, a grain free would be better then Purina One but I found alot of grain free kibbles have potatos & you need a low carb diet, yeast loves carbs, I few people I know feed the “Holistic Select” Anchovy, Sardines & Salmon meal, for their dogs with bad skin problems & they say its excellent the vet diets never helped their dogs, the Holistic Select also has 2 grain free kibbles Deboned Turkey & Lentils has no potatos & their Salmon Anchovy & Sardine grain free…or you can do an elimination diet to see what foods make him itch, but an elimation diet takes time…Wellness has their Simple limited ingredients range, that way he’s having limited ingredients, less ingredients to make him itch, also sardines in spring water are excellent for itchy skin, I give a couple sardines as a treat…I’m using the Wellness Simple Lamb & Oatmeal as my boy cant have potatos or sweet potatos, he’ll break out in a rash all over his stomach & chest, then his ear starts to itch, then his paws go all red & itchy, its awful.. I wouldnt believe it if I didnt see how a little bit of potato can do all this, I found this out buy doing an elimination diet…maybe try raw thats the best for skin problems, cooking or raw works out cheaper then kibbles, ..
