Designed for superior flight, our 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 super fun, but also bite-durable, water-resistant, floats, and has a canine-resistant cap. Available in our fun, color changing Disc-O LED color, the Dog Discuit comes with two replaceable, long-life CR2016 3V batteries for up to 20 hours of fun under the stars.
