It's important to use the right size KONG toy to have the safest, most enjoyable, and longest-lasting experience. If your dog destroys a KONG toy in a short time, try a larger size. If you have multiple dogs in your household, only provide KONG toys sized for the largest and/or toughest chewer in the house. Example breeds are intended as a guide only as every dog has a unique chewing temperament and it's not necessarily predictable by size or breed. Even the smallest dog may be more tenacious than a dog four times bigger. KONG recommends the toy is always larger than the dogs mouth.
