Hummmmm....look at the ingredients list...does that food contain any wheat, barley, rye, soy, dairy, corn, beef, chicken, rice or turkey? If it does, he has probably developed an allergy to one of these ingredients. I would suggest switching to Natural Balance Sweet Potato & Fish formula or Natural Balance Duck & Potato formula. Both of these are the very best foods for allergies because of the "exotic" ingredients. |
