Abstract: An animal diaper system retains a disposable absorbent pad against an animal. A cross support has a girth portion and a longitudinal portion, wherein the girth portion has attachable distal ends for securing the girth portion around the animal. The longitudinal portion extends from the girth portion and has a tail end and a front end for fitting along the underside of the animal. The longitudinal portion comprises a pad-receiving area between the tail end and the girth portion. Rear straps are adapted to pass from the tail end between the hind legs of the animal and around respective sides of the tail of the animal to attach to the girth portion at the top side of the animal. A pair of suspender straps are adapted to pass from the front end through the front legs around respective sides of the neck of the animal to attach to the girth portion at the top side of the animal.
