Marcello Ziliani and Tobia Repossi designed this funny dog litter bin for off-leash areas of cities. This is the first of a series of products that the pair will design for Holzhof, the leading company in the production of structures for playgrounds and urban furniture, which recently acquired Modo. The Dog Bin is called Bau Bau, and it also comes with a fountain for the happiness of your pet friend.
