I have read a lot of posts recommending Zinc Oxide for nose sunburn on horses. My concern is that this product is marketed for skin protection on babies (diaper Rash). It also has warning labels for ingestion, to call poison control. My question is; is it safe to apply to a horses nose where he can "lick" it from his skin. Zinc can be toxic. Does anyone know for a fact (IE; a vet etc.) that ingesting this will not harm the horse?
Thank you for your help.
