KONG Blue is the strongest rubber dog chew toy available today. Made from a newly reformulated rubber, it's puncture resistant and gives even the strongest chewers a healthy workout. KONG Blue's center can be filled with treats or food to keep your dog busy for a long time. Vet's recommend KONG toys to help relieve stress, boredom and provide playful exercise.

But, the best part about the Blue KONG™ is they're radiopaque which means if your dog is able to swallow a piece of this toy, the special material will clearly show up on an X-ray. Something most other rubber toys can't do.

No dog toy is indestructible. Supervise your dog's use of KONG toys until you are confident they can be used without supervision.

Sizing tip: If your dog destroys a KONG in a short period of time, switch to a larger size. Regular use of a KONG toy will strengthen a dog's jaw muscles and you may need to size up periodically.
