1) Wheat, barley, rye - ALL of these grains. (including bread, snack crackers, treats, etc.) Oats are the safest grains from an immunlogical standpoint (least allergy-producing)
2) Dairy products - ALL of them. (including milk, cheese, whey, casein, dried skim milk, etc.)
3) Soy - ALL of it.
4) Corn- (including corn gluten meal)- Try to eliminate as much of this as possbible. Eliminate ALL of this whenever possible.
5) Beef - (only if allergy symptoms are present and persistent. This is the most common secondary allergen in dogs)
6) Artificial preservatives and colors - (You want to see preserved with vit.E)
