This is a Beef Trachea that has been baked into a ball shape. Each piece is about 3-4" in diameter, and weighs about 2-3 ounces. There will be some variation in shape and size. A Tuesday branded ElastiBand with UPC is wrapped around each piece.
Trachea are a great natural source of glucosamine and chondroitin, two essential parts of maintaining joint health.
Due to the slightly higher fat content, trachea bites are an extremely palatable treat for most dogs.
