Abstract: A retractable harness device for use as part of an animal hygiene system particularly for dogs. Comprising a housing attaching at its forward facing edges to an animal's harness by means of straps. From apertures in the housing extend two cords which are payed out along a dogs back under tension from retractable mechanisms within the housing. Releaseable bag-attaching members with stop guards are permanently joined to the ends of the cords. The attaching members attach to corresponding points on a suitable waste collection bag securing the bag beneath the the animal's tail in order to collect solid waste. The device may incorporate a tensioning mechanism to increase tension on the extended cords to allow for the body movements and additional weight of deposits of larger animals.
