tizliz, I would have pm'd this to you, but thought it might interest others.
If not, please ignore. What is Gluten?
Gluten is a protein that is found mostly in wheat but is also present in other cereal grains, including rye, barley, oats and buckwheat. It actually is a crude mixture of two other proteins, gliadin and glutenin. Grains that do not contain Gluten are rice, amaranth, millet, corn and quinoa.
What Does Gluten Do to Intolerant Dogs
Most dogs tolerate wheat and other grains quite well and have no adverse effects from having them in their diet. Unlike cats, dogs can process both meat and plant products. Gluten normally is digested by pancreatic enzymes in the small intestine. However, some dogs – like some people – cannot tolerate gluten. In people, this condition is called “coeliac disease.” In dogs, it is called “gluten-induced enteropathy,” “gluten intolerance” or “gluten sensitivity.” Dogs that are sensitive to gluten develop a chronic small intestinal inflammatory disease if they eat gluten. They have intermittent or persistent diarrhea, lose weight, develop a poor hair coat, lose body condition and just generally fail to thrive. Fortunately, gluten intolerance is not common in companion dogs
How Does Gluten Cause Digestive Problems?
Dogs that are allergic to gluten have a delayed hypersensitivity (allergic) reaction when they eat food or treats containing cereal grains. Although the exact pathway of this disorder is not well-understood, it is thought that a gluten-intolerant dog’s immune system attacks its gastrointestinal tract when it comes into contact with gluten, damaging the tiny, hair-like projections lining the small intestine, called “villi.” Damaged villi can’t absorb key nutrients, such as proteins, carbohydrates, fats, vitamins, minerals and, in some cases, even water. As a result, affected dogs are malnourished even if they are eating a lot of food. They will lose weight and body condition and develop chronic diarrhoea
