Hi, it could actually be the chicken that is causing the hives, itchiness, and allergy symptoms. A lot of bullies are allergic to chicken, including my female Blossom. We switched her food 4 times before we found one that she tolerated. She used to get pink skin, itchy paws, licking her paws and pink warm ears. We switched to Fromm's Beef Frittata grain free 21 months ago and she's been fine since then.
