The KONG® DuraMax™ Ball is specially designed for chewing satisfaction for dogs who can't get enough of it. The KONG® DuraMax™ Ball is made from extremely durable K-100 material that yields just enough to be irresistible while withstanding long-lasting chewing fun. Dogs especially like the textured surface reminiscent of fish scales, which adds variety and can help clean teeth. A squeaker adds to the fun and encourages long-lasting chewing and play sessions. Note: Please never leave the pet unattended while playing. No toy is indestructible. To prevent injuries, the toy should be checked regularly for damage or loose parts and replaced if necessary.
