According to Nestle, Nesham, true allergies are an overreaction of the immune system to foreign proteins.  In humans, 90% of allergies are caused by: milk, eggs, peanuts, tree nuts, fish, shellfish, soy, and wheat.  There's no stat on % for dogs.  Best route for treating allergies seems to be the elimination diet which takes forever, but will enable the identification of the trigger food.  Alternately, you can try switching commercial foods till you find one that doesn't have any adverse effects.  I'm trying the home-cooked route with ACV spray and the odd anti-histamine tablet when necessary.
