Pooper-scooper
A pooper-scooper, or poo scoop, is a device or a ‘poo bag’ used by pet owners to pick up an animal's fecal matter from public places and yards.  Such devices often have a bag or bag attachment.  The ‘poop bag’ is usually turned inside out, to carry the feces to a proper disposal area. The person performing the cleanup might also be called a pooper-scooper.
