Dog Food Allergy Symptoms

Like people, dogs can suffer from food allergies. Food allergies are not as common as flea allergies or environmental allergies, but they can cause uncomfortable symptoms in as many as 10 percent of all dogs. Corn and wheat are the most common food allergens.

  1. Itching

    • Itchy skin is the most common symptom of dog allergies. Watch for excessive scratching, especially around the face.

    Recurrent Ear Infections

    • If your dog suffers from recurrent ear infections and you can't find the cause, it could be a food allergy. Ear infections cause itching, swelling and a foul odor.

    Hot Spots

    • Ulcerated sores known as hot spots may appear, especially on the legs or feet. Your dog may lick these spots incessantly, making them worse.

    Chronic Skin Infections

    • Chronic, ongoing skin infections often plague dogs with food allergies. Yeast is often the culprit.

    Increased Bowel Movements

    • If your dog has three or more bowel movements a day, it could be a sign of a food allergy. Typical dogs have one or two bowel movements a day.

    Food Allergy Indicators

    • It may help to change your dog's diet to one based on lamb and rice. If symptoms persist year-round and don't respond to antihistamines, consider having her tested for food allergies.
