KONG® SIGNATURE DOUBLE RING TUG consists of two intertwined rings of braided rope. The combination of cotton and fleece is robust yet soft, so that the sensitive skin of the four-legged friend's mouth is protected during extensive tugging and chewing. The double rings invite you to play together - for twice the fun. Note: Please never leave your 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.
