Play, fun and chewing pleasure - The KONG® Dental dog toy is designed to satisfy a dog's instinctive needs. Made from the unique red KONG® Classic natural rubber, KONG® Dental has special grooves that cater to a dog's natural chewing instinct and help clean teeth. Snacks and pastes can be filled in the grooves and inside for long-lasting activity. 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.
