My dog with allergies does best on Nutrisca salmon and chickpea (no grains, no potato). But since receiving care by a specialist/dermatologist she can tolerate a variety of foods as her allergies are environmental. She had IDT (Intra Dermal Testing) and has responded well to ASIT (Allergen Specific Immunotherapy)

PS: I sometimes bathe her twice a week (approved by the specialist) with Malaseb or Antifungal dog shampoo by GNC I like the lavender smell.

I don’t agree with all of the opinions expressed. Hope this helps.
