Rye in dog food
Rye is a high quality grain with a nutritional profile fairly similar to that of barley. It is one of the three 'gluten-grains' (the others being wheat and barley) making it unsuitable for celiac dogs or many dogs with grain intolerance. As with all grains, rye is best in its whole grain form as it retains much more of its nutrients.
