Natural Instinct's Beef Pipes are a complementary treat made using 100% dehydrated beef trachea. One of our best-selling treats, this tasty trachea, can be fed directly from the packet or stuffed with one of our mouth-watering recipes as an extra treat. Bursting with flavour, great for oral hygiene and a natural source of glucosamine and chondroitin, the building blocks for cartilage, our Beef Pipes are the perfect choice for growing dogs or elderly dogs with joint issues.
