Hi, yes it's possible to get hives from almost anything. Hives are a symptom of an allergy, and both people and dogs can have allergies to almost anything. A lot of bullies are allergic or sensitive to chicken, so it is possible that your bully is allergic to the chicken flavouring on the bone.
Thank u all.im trying to finger out what the heck is going on with him.I feed him blue buffalo "freedom" and I also make his food. I boil chicken grand it.and I boil sweet potato, carrots, peas, and blueberries. Oil and enzyme and probiotics.he dose fine.its just all of a sudden when I gave him a new chew toy and before bed time I noticed hives. Thanks again.
