Autoimmune problems cause allergies and malnutrition can cause allergies. Malnutrition can be because of long term diarrhea or a heavy parasite load, as well as an unbalanced diet. Actually anything that causes inflamation to the gut can cause allergies/intolerances. A gluten or grain intolerance can lead to other allergies because of the inflamation that the grain caused, same with others. So having one untreated intolerance can lead to others, which is one reason I’d like to throttle vets who give cortisone shots instead of having the owner do the work of getting to the bottom of the problem. And also why my intolerant dog always gets digestive enzymes with his food, even though he isn’t eating anything he is intolerant to.
