As is true for humans, there is a difference between food allergies and food intolerance in dogs. Food intolerance typically produces gastrointestinal symptoms like vomiting and diarrhea while food allergies produce allergic reactions like itching and skin problems. The treatment for food allergies and food intolerances is the same – avoidance of the offending food.


Signs and Symptoms of Food Allergies


The symptoms of food allergies in dogs are similar regardless what type of food is causing the reaction. The most common symptom is intense itching, especially on the face, feet, ears, and forelegs. Some dogs experience chronic or recurring ear infections as well as hair loss, hot spots, and recurring skin infections that do not respond to treatment. Excessive scratching is a common sign of food allergies, as is increased frequency of bowel movements. It can sometimes be difficult to distinguish between food allergies and atopic (contact) allergies. A common sign of food allergies is that the symptoms persist all year round and if skin problems do not respond to medical treatment.


Treatment for Food Allergies


The best way to identify your dog’s food allergen is to conduct a food trial. During a food trial you would feed your dog a diet that consists of a novel protein and carbohydrate for 12 weeks until all signs of the allergy have disappeared. Novel protein sources might include rabbit, venison, or even kangaroo while novel carbohydrates include things like sweet potato or brown rice. After the 12 weeks you would then introduce common food allergens back into the diet one at a time and watch for a reaction. Once you have identified the culprit, you then simply need to keep your dog on a diet that does not contain that food allergen.


Food allergies in dogs are becoming an increasing concern with pet parents, and there are more formulas on the market that eliminate the offending ingredient while providing all the nutrients your dog needs. If you suspect that your dog is suffering from a food allergy you should consult with your veterinarian and take steps to identify the allergen and then eliminate it from your dog’s diet.
