This LED Dog Collar is slightly different from the rest – while others come with just a blinking light to help capture your attention at night (especially for folks who own totally black dogs like Labradors), this model sports a full LED collar. Yes, the whole collar will light up whenever it is worn, making your four legged friend a snap to spot from afar. You can also choose from slow flashing, fast flashing and having it being turned on constantly, depending on how far you want the collar’s battery life to go. It is flexible enough for virtually all dog sizes, where the steel D-ring makes it compatible with just about any leash. Nice to know it ships with batteries included as well as a couple of spares to get you started right out of the box at $4.95 each.
