An improved animal waste disposal device is an expandable container that attaches to a pet owner's lower leg via hook and loop straps, for carrying animal waste. The device has a separate attached lower compartment for holding a roll of plastic bags for holding the waste, that are individually dispensed through a slot in its front cover. The front and the top of the top waste compartment hinges at the outer bottom edge and pivots outwardly, remaining attached to the back side with accordion style sides that attach to the front and back sides.
