No, this is not an SNL sketch.

After many years of painstaking experimentation, engineers have designed a state-of-the-art dog washer. Using experimental "hose" and "hula hoop" technology, the "Woof Washer 360" is a hollow ring that shoots out water from every angle, ensuring that your dog gets clean without the hassle of sponges or baths. Patent is still pending, but cheap knockoffs like the "Bark Scrubber 720" or "Ruff Rinser 900" will never be able to replace the ingenuity of this hydraulic tennis racket. Maybe one day, science will progress to the point where there's a human model. We can only hope...
