Loved by Dogs. Backed by Science. Big kibble companies don't want you to know it, but studies clearly show that canines are healthiest when they avoid carbohydrate as much as possible. Keto is a dog's natural diet. Your Dog wasn't built to eat carbs. Feed her as nature inteded with Ketona, the world's first truly low-carb kibble. Less than 5% digestible carbohydrate and more than 50% protein.
