Taking your dog out for a walk at night can be a real pain. Once you let them off the leash, it's pretty hard to spot them in the dark. That's why this neck collar with a built-in LED light can solve that problem. With a click of a button you can scroll through several different light options from repetitive flashes to a constant light. Since the collar is around your dog's neck, he/she won't be bothered by the flickering lights. The high grade nylon webbing is durable and built to last. Fully adjustable from 17 to 23. Perfect for rottweiler, labrador and similar sized breeds.
