A pet drying and cleaning bag is made of a piece of material having two opposite ends joined together to form an open-ended material. One of the unjoined ends is kept fully open while the other unjoined end is partially joined together, leaving an opening in at least a portion of this other unjoined end. This opening may be closable and may also be elastically expandable. Some embodiments of the pet drying bag may include closure mechanisms, such as zippers or hook and loop fasteners, to provide additional openings in the bag. The bag of the present invention may be made larger to act as a beach bag, towel, and privacy changing screen.
