Dog belly band size medium

Belly band is for preventing male dogs from lifting their leg and peeing on your furniture!! This is size medium. It is hard to measure but the total length is 17.5". The velcro is about 4" and the edges are elasticized. This band can fit dogs from about 13.5" to 17". It fit on my dog that was 17lbs. Please carefully measure your dog. This item does not have any stains or flaws. I also have a size small listed as well.
