These bones have made crate training a breeze. My dogs are happy to go into their crates and lie down when they hear the Sportmix box being opened. With all of the scares about poisons in the treats made in China I wrote to Sportmix before I bought their products. Here is the lovely reply I received. "Thanks for choosing to feed your dog our SPORTMIX dog biscuits. Our Sportmix Biscuit treats are manufactured in our company owned manufacturing facility in Monmouth, Illinois, USA. Midwestern Pet Foods was founded in 1926 as a miller of flour and corn meal. In the 1940s we began using the basic ingredients from our milling operation to produce pelletized dog and cat food. A family owned business, now in its 4th generation, Midwestern Pet Foods owns and operates three state-of-the-art, pet food production facilites in the Midwest and has expanded its pet food production to include natural holistic pet food, biscuits and treats." My UPS delivery man carries these treat biscuits and he is a favorite in my neighborhood. I recommend all of the Sportmix biscuit treats and am grateful to Amazon for carrying the 20 lb. boxes.
