New Model 3800X is the latest addition to the Doggie Dooley dog in-ground waste disposal range. All Doggie Dooleys are in-ground sytems; the model 3800X is one of the leachbed (open base) systems, and requires less assembly than models 3500 or 3800. It also has a greater capacity if needed (by digging a deeper, narrower hole undeneath the main hole which hold the unit). Manufactured in America, this model has quickly come to rival the Model 3000 septic tank system as the best selling unit in the Doggie Dooley range. As with all Doggie Dooleys, either terminator tablets of digester powder can be used in this unit to help break down the dog waste so it can drain harmlessly away into the ground. The ideal way to dispose of dog waste in a clean, safe and environmentally friendly way. See the whole range here
