David said: There are some nonallergenic dogs, so depending on the breed, it may or may not be an issue. As we discussed last night, allergies - Immune amphoterics, Immuno-regulatory herbs, alteratives, red, hot and dry = Gotu Kola, Burdock Seed, Milk thistle seed, and Sarsaparilla, as a starting point. Check bowel function, gut integrity, liver function.
