Our gourmet smoked beef marrow bones are made with 100% all natural hardwood smoke. We never bake or dehydrate our bones because it weakens the bone. Also, we NEVER use liquid smoke, additives, preservatives, mold inhibitors or any other harmful chemicals that can cause health problems for your pet. Instead we only use 100% all natural, farm raised, grass fed, USDA inspected beef. To smoke our bones we use an old Southern, 100% all natural smoking technique that serves as a natural preserver for the marrow, the meat and the bone itself. Our process of low temperatures and slow smoke not only strengthens the bone but it gently infuses all of our bones with a delicious hickory flavor and keeps each bone packed with a delicious marrow your dog will absolutely love. Each of our bones contain three treats in one; the bone for chewing, the marrow for flavor & the remaining beef jerky on the outside of the bone for protein! Our small bones are not only the perfect treat for small breed
