Dental Kong with chew clean grooves perform a gentle "squeegee" action on teeth and gums when chewed. Removes food debris and reduces plaque and tartar buildup. Kong satisfies a dog's natural need to chew--the thick, flexible walls keep springing back for more! Made in the USA. For Maximum Safety: Supervise use. Inspect toy frequently. Remove damaged toy. Important Safety Information: No dog toy is indestructible! All dogs have powerful jaw muscles and sharp teeth. Most dogs chew 40 to 60 times per minute with a force of 1,200 to 1,500 pounds per square inch. Kongs are safe, beneficial toys designed by people who know and love dogs, but ultimately, your dog's safety is your responsibility. Every dog is a unique individual and no one can predict how long a Kong will last with your dog. Note: If your dog destroys a Kong in a short period of time, it is probably too small. Regular use of a Kong by your dog will increase jaw strength, so you may eventually need to provide larger red or black Kongs. Supervise the use of toys. Frequently inspect the clean toy under a bright light. Look for damage (such as missing pieces, cracks, separations). Flex the toy and inspect it from differenct angles. Loose pieces larger than a food nugget can be harmful if swallowed. Worn or damaged Kongs must be replaced promptly to maintain safe play for your dog! If you think your dog has swallowed a toy fragment, inform your veterinarian. Dishwasher safe.
