The Jones Natural Chews Windees (medium) are made of USA-raised beef trachea or windpipe. Windees are oven-baked to perfection for a smoky, rich flavor with no artificial ingredients included and cut to 6” an appropriate size for medium to large size dogs. These are a natural source of glucosamine and chondroitin, which both aid in improving joint health and are good for all chewing types. The crunchy texture offers a unique chewing experience that dogs love and dog parents can appreciate that this chew offers such great health benefits. This single-ingredient natural dog chew provides hours of tasty chewing entertainment. All Jones Natural Chews’ products are raised and handcrafted in the USA and responsibly sourced.
