Designed for superior flight, the Flashflight LED Dog Discuit is a soft-touch plastic flying disc made specifically for nighttime play with your disc-loving dog. It's illuminated by a super-efficient, long-lasting LED, so it glows brightly in the dark. The Dog Discuit is not only fun, it's mouth friendly, bite durable, and has a protective canine-resistant battery and LED cap. Available with a color changing Disc-O LED, the Dog Discuit comes with two replaceable, long-life batteries, for endless seasons of fun under the stars.
