Apparatus are provided for collecting pet waste. In embodiments a grapple coupled to a housing is selectively operable between a closed position in which the grapple and housing substantially enclose a body compartment and an open position in which the grapple and housing define a mouth in communication with the body compartment. A handle is coupled to the housing, and a grapple control on the handle is configured to selectively operate the grapple between the open and closed positions. The grapple control may comprise a grip lever. A bag roll may be supported inside the body compartment by an axle mount. Bags may be unspooled from the bag roll and, without being torn from the bag roll, placed over a portion of the housing and the grapple to provide a sanitary barrier between the apparatus and pet waste.
