Theo is allergic to wheat and grain. If he eats it, he will often get an ear infection, begin scratching himself a lot and gnawing his paws. If you see your dog exhibiting the same behavior, try changing his/her diet. I feed him Taste of the Wild (with Roasted Bison & Roasted Venison formula) and he loves it. More importantly, it stopped the itches. It is a little more expensive but I feel good about feeding him great food. I want my munchkin to live forever.
