Size: Rear Girth XXS 8″10″ XS 10″-13″ S 13″-15″ M 15″-18″ L 18″-20″ How to Measure Your Dog: Measure your dog’s rear girth (lower tummy) with a tape measure. Add approximately one inch to the measurement to accommodate a disposable incontinent pad. We recommend using a disposable incontinent pad for maximum absorption and hygiene, as the pads are specifically designed to pull moisture away from the dog’s tummy, keep the skin dry, and neutralize odor.
