The Woof Washer 360 is a hula hoop shaped gadget that sprays water so you can wash your dog more easily. Just connect your garden hose and you can get Rover clean super fast.
You can spray soapy water through it, or clean water for rinsing. It looks like a pretty awesome gadget, but also kind of ridiculous. It does look like a much better option than putting your dog in the tub and having him get the whole room wet and filthy as you fight with him.
The Woof Washer 360 costs $19.99(USD) for the small version and $24.99 for the large and comes with a microfiber drying mitt. Whether this thing works or not, it looks funny to use. It might be even more useful for cats.
