The Dog Discuit from the Flashflight Family of light-up, flying discs is another great one. The LED console with push-botton on/off switch is very well protected against the sharpest of all puppy teeth. The gummy yet, hard durometer rubber holds up well so you and your best friend can fetch it all day and all night - day after day! The Discuit is 8.5" in diameter and weighs 130g. And, when you wear out your dog, you can have fun tossin' it around with friends after washing it clean because it’s water resistant too!
