This dummy training collar is an excellent tool for the homeowner or trainer. Use this dog training collar as a way to introduce the weight and feel of a training collar to your dog. Once you have trained your dog to stop barking, you can use this collar as a reminder if your dog shows signs of regressing to their old barking ways. A lot of times just placing this fake anti bark collar around your dogs neck will be enough to reinforce all that training you have done.
