Keep lawns and play areas clean and sanitary with the Doggie Dooley. Requires some easy assembly and digging a hole (approximately 1 hour installation time from start to finish). Simply install in the ground, drop in dog waste, and occasionally add Digester and water for continuous break down of waste. Works like a home septic system by using Enzyme and Bacteria action to turn waste into a ground absorbed liquid. Improved plastic construction and materials makes this our most durable unit to date providing years of in-ground service. The Doggie Dooley is harmless to lawns, pets and shrubs and has the capacity to handle the waste of 1 large dog to 2 small dogs. Each unit comes with about a 6 month supply of Digester (depending on usage) and has a step on lid opener. Can be used in cold weather areas provided the unit is installed following Winter-time directions to dig below the frost line. Works well in all soil conditions except hard clay and heavy sand. Doggie Dooley, since 1968!
