Wall AG's integrated concept Dog Service combines innovative services and high-quality products to form a clean, ingenious all-in-one solution. Dog Service consists of two complementary innovations. One is the Dog Service Station with its odourless dog waste disposal unit and eco-friendly paper bags. The other one are the mobile service units, staffed by Wall AG or our cooperation partners' employees. The patrol parks and streets and inform dog owners about their duty to clean up after their pets. For clean streets, parks, and squares. For a better quality of life in our cities.
