I don't like disposable diapers for dogs. I bought each of my furgirls a pair of panties from Go.Fetch (YT vendor). I cut poise pads in half, and put these inside-it makes them easy to change, keeps the girls from marking in their sitter's house (the only place they do it), and they look just adorable when they're on

Plus, it's much more cost effective to buy two reusable panties and a pack of pads that will last forever.
