O my!!! That is a bad looking rash!! Our Riley who is allergic to many things NEVER had a rash like that!!!! Can your boy eat the z/d canned(which Riley was allergic to)instead of the dry? I think the dry has BHA, BHT, and ethnquion(sp) as perservatives. Riley is doing well on the canned EVO and for a treat gets some goats' milk(HE LOVES MILK). PLease keep us posted....Prayers of healing and comfort out to you and Bobby....
