They make belly bands with harnesses, but they are about $20! I buy mine for $5 eaqch on eBay or on Etsy. The stores want about $15 for regular belly bands! I don't have a sewing machine, or I would make them myself. I tried several things, but but found that they just don't work as well as a real belly band. I like the ones with elastic.

I got so fed up with stepping in dog pee!!!
