My vet told me that the top food allergens are:

1. Corn
2. Beef
3. Wheat


Look for a food without these ingredients. Itching and biting the fronts of the legs until they are raw is a common sign of allergies. Could be food allergies, could be environmental allergies. It is hard to tell. Try the food first. It could take up to six weeks before symptoms disappear if it is a food allergy.
