What kibble are you feeding now? You can try sample sized bags of premade raw. Nature's Variety, Stella & Chewy's & Primal has them.
Have you done a skin scraping & cytology to determine what could be causing the itchies? It doesn't cost much & they look under the microscope to see if it's bacteria or yeast related.
My guys eat premade raw for 1 meal & kibble for the other & are doing great. Canned food is an excellent topper as well. I would like to switch them to exclusively raw, but it's kinda pricey to feed 4 mouths. If I was to go PMR, it might be more affordable but I'm not @ that level, comfort wise...yet.
I have 2 w/enviro allergies & yeast (skin cytology confirmed this), they used to lick their paws excessively & always have a 'frito' smell. They were even on temaril-p for awhile, but now are doing 90% better. I've also eliminated all 'sugary' foods from their diet & no more store bought treats. Hope this vid helps, it helped us tremendously:
