A pet leash and waste pick-up device comprises a retractable waste pick-up tool which is conveniently disposed in a sheath housing compartment on the leash device. When it is necessary to pick up and dispose of pet waste, the tool is removed from the sheath housing, expanded to a usable orientation, and fitted with a plastic waste bag. The device is then maneuvered so that the center of the bag is positioned over the waste to be removed. At this point, the tool is retracted, thereby closing the bag over the waste. The bag can then be simply removed from the tool, sealed appropriately, and stored for disposal, without risk of the user directly contacting the waste.
