To use it, just fill up the container with any dog shampoo you have, attach the washer to your garden hose, and start giving your dog the shower they've always wanted. The water and shampoo mix instantly as the water runs through the washer. There's also a button to put the device into rinse or suds mode, so you can choose when to apply the soap and when to rinse it off.
You can adjust the hoop to accommodate any size dog, just bend the hoop out to wash larger dogs, and push the ends inwards to bathe smaller dogs.
No longer will bathing your dog be a chore that you and your dog hate. Now you can just bring them out into the yard, and give them a calming dog bath that they will think is just a nice little massage.
The Woof Washer connects to any standard garden hose, folds up for easy storage, and when fully setup measures 16.9 inches in diameter, x 1.2 inches thick.
