The Doggie Chicken Chips are cold formed and dehydrated at constant temperature of 155 to 160 degrees for 8 hours. By dehydrating the chicken rather than baking the chicken, the chips capture all of the nutrients for the benefit of the dogs. Heat from baking destroys the enzymes in chicken. The enzymes found in chicken helps the digestive system, makes stronger blood cells and indirectly helps the animal maintain good weight.
