Browsing Amazon today I found this contraption; a home pet spa. Solving a lot of the frustrations of bathing dogs, the Pet Spa features a hand-held wand for reaching those ‘hard to wash’ areas, the side mist jets help ensure a thorough rinse, and the tall sizes help eliminate you from getting soaked by a shaking dog!
It has a connection to your plumbing and a flexible drain hose. It also features an adjustable platform to fit dogs of all sizes!
It just goes to show, you can find anything on Amazon!
