Our beef marrow bones, sourced from weight-bearing bones, are slow roasted with small amounts of liquid smoke for an added flavor.  Each piece is shrink wrapped and sliced to a 7" length, revealing a rich center of healthy fats such as monounsaturated fatty acids that promote heart health (in moderation). Recommended for large adult dogs, these bones provide a long-lasting chew that satisfies the pickiest of eaters. Additionally, the surrounding meat and tendon make the marrow irresistible to dogs. However, due to their density, these weight-bearing bones are not recommended for dogs with underlying dental issues. Analysis shows a minimum of 30% crude protein, 15% crude fat, and a maximum of 6% moisture and 3% fiber. Chew Time: Super Tough.
