The breeds above are just suggestions and may not be accurate to size. Please measure your dogs neckto be positive the collar you order will fit. Ultimately dogs can be lean or chubby, hehe, so it is hard to "guess" the size based off breed.
Taking your dog out for a walk at night can be difficult and dangerous. Once you let them off the leash, it's pretty hard to spot them in the dark. This collar with a built-in LED light can solve that problem! Since the collar is around your dog's neck, he/she won't be bothered by the lights.
