LED Dog Collar This is a little different than the rest – while others come with only a flashing light, to capture your attention during the night (especially for people, the dogs have quite so black Labradors), Sport model presents a complete LED chain. Yes, the necklace lights up when all will be displayed which makes your four-legged friend a look from afar to see. You can also choose to flash, slow, fast and lights were flashing, depending on the distance you want the life of the battery to go to the collar. It is flexible enough for virtually any size of the dog, where steel D-ring, makes it compatible with almost all hands. Good to know that it comes included with batteries and some spare parts to get you started right out of the box on each $ 4.95.
