I was considering doggie diapers too, didn't end up getting any because the meds actually helped, phew! I considered the cloth ones too, or even just pants for bitches in heat that you can put pads in. Never got as far as to test it out so hopefully, someone else can advise you. But I did try a human baby nappy with a hole for the tail, and it kept sliding down every time she walked three steps. Could be just that brand/design/size that didn't work out, but I gave up on it pretty quickly.
