The Jones Knuckle will contain either a femur knuckel or saddle knuckle that is cut from USA-raised beef, dipped in natural-liquid smoke and oven-baked to perfection. Generous portions of meat and cartilage are left on these bones for a tasty, protein-rich chewing experience that is free from artificial ingredients. These are an appropriate and long-lasting, natural chew for medium and large sized dogs. The gnawing action that occurs during chewing does help keep dogs' teeth and gums clean, making this bone a great option for preserving dental health. All Jones Natural Chews' products are raised and handcrafted in the USA and responsibly sourced.
