This is a dog training collar. It also stops the non stop barking. It comes in different colors and is easy to assemble. It runs on batteries and the color i chose is navy blue and black. The case it comes in is very nice for when your dog is finished with training or doesnt need to wear that collar. This collar is very effective at stopping dogs from barking like crazy at nothing. I would recommend to others looking to train there dog. I received this product for free in exchange for my complete and honest review.
