Milk-Bone chicken treats typically list protein in the mid-teens (about 15–18%), and include multiple vitamins and minerals (commonly a dozen or more, such as iron, zinc and vitamin B12). Many formulas also show calcium and phosphorus, and some note added omega-6 fatty acids. Certain mini varieties are described as low-calorie per treat; calorie counts vary by product.
Milk-Bone chicken treats are labeled for a range of dog sizes—from minis up to large—and for life stages listed as adult or all life stages. Dental chews are typically intended for dogs over six months, with size recommendations such as 5–24 lbs (mini), 25–49 lbs (small/medium), and 50 lbs and up (large). Check the package for the product-specific recommendation.
