an intolerance occurs when a dog has difficulty digesting or processing a particular food. when a dog has a food intolerance, you may notice that they are able to eat small amounts of the food without having an immediate reaction. you may also be able to prevent a reaction
how to feed
when dogs eat foods filled with corn, wheat, soy, gluten and grain they tend to have a reaction in their digestive system (this we call a food intolerance). food intolerances are far more common than food allergies and can result in a reaction that takes place over a longer period of time
intolerances are different than allergies as allergies trigger the immune system and intolerance is mostly limited to the digestive tract.
