Our town had a new car wash open recently and it also has 3 bays for do-it-yourself pet washing. Just put in your $2 and select your shampoo choices-doggy, puppy, oatmeal or flea and tick. Then wash your pet, add conditioner and rinse. The black hose to the top left is for vacuum drying.
This is hubby Jeff washing our dog Theo. They were both enjoying it more than the pictures look like though. And I really like that there is no messy bathroom to clean afterwards.
