Nite-loving dogs need NiteDog, it’s that simple. The NiteDog Rechargeable Pet Light features a weather-resistant polycarbonate housing with a mount that threads onto leashes, collars, and harnesses up to 1” wide. Its bright Disc-O Tech module enables you to choose from 4 selectable colors of red, green, blue, and white in glow or flash, plus color-changing Disc-O mode for a fun, seamless color blend. Portable and lightweight, NiteDog recharges in 2 hours with a Micro USB cable (not included), ensuring you can always keep a careful eye on your pup from the sidewalk to the campsite.
