It's a wearable combination sprayer-scrubber that can be easily turned on and off. It gives you total control over your pet and the flow of water during the entire bathing process, eliminating much of the time and fuss involved in bath time. This device puts everything you'll need right in the palm of one hand, so you'll have the other hand free to herd your dog and keep them in place. Comes with 8 ft/2.5 meters hose and connects to your garden hose with adapters which are included.
