This Mikki collar and harness is a way to get your dog to stop pulling on their lead when you take them for a walk. This effective training aid uses the dogs own natural reaction to the pull to make them stop and walk by your side, so you don't have to use excessive force to pull them back. Ideal for short nosed breeds or dogs with delicate facial features. Also good for nervous dogs who get scared easily while on a walk. The collar that is included in this pack is adjustable and reflective, so you can even use it on your night time walks; as well as a snap lock for safety so its easy to get your dog out of trouble if it occurs.
