(Nylabone) A great choice for your dog! Only the finest ingredients are used in these healthy chews. With no added plastic, sugar, salt or colors, you can feel good about serving these low-fat Nylabones. Bone-hard texture wears down slowly to aid in tartar and plaque control. Specified bones can be microwaved for under a minute to achieve a softer biscuit-like texture. Nutritious and delicious!
