This touch-less dog washing mechanism is the perfect solution for your pet shower. It's basically a plastic ring that you hook up to your hose outside, and you put the dog shampoo in a little piece that screws into it. Your dog gonna walk through the loop and so all the little spray nozzles will spray the shampoo and water on him. This is a one size fits all, dog-wise. It's adjustable for small or large dogs as the rings expand and contract.
YOU'LL JUST NEED TO MAKE SURE THAT THE WATER IS NOT TOO COLD. THAT IS SIMPLY IT!
