In humid weather, dogs get very durty. If a dog owner lives in a multistorey building, everything – stairs, lift, appartment – get durty.
A very simple public outdoor dog washer could solve the problem. It could be a free service or a business. If it's a business, the dog washer could be implemented as a self-service coin-operated device. Thus, only dog owners will bear the cost of the service.
