These are measuring in above 9". For any sized dogs, this is a natural way to supplement hip and joint health due to the dense concentrations of hyaluronic acid the body uses to manufacture its own glucosamine. For dental health, we call it nature's floss due to the stringy fibers as it breaks down. These are strong tendons with a forked end that gives dogs a good starting place to work. Your dog will thank you for the quality of this product.
