A small animal harness comprising an elastically deformable forechest pouch for carrying a ball, snacks or other objects. The pouch is carried by a quadrilateral base member to which is attached a pair of flexible shoulder straps and a pair of flexible brisket straps whose ends converge over the animal's withers into a rigid connection plate so that the brisket straps are slidable within the plate and extend outwardly to be connected to a leash.
