There are a couple of YT members that have re-usable panties (I think you're going to want panties instead of belly bands since you have a girl
). Here's one:
Panties/Belly Bands - Panties - The Chloe Bella Pet Boutique
Are you not planning to spay? I only ask because I just rushed to get my little girl spayed since she's 6 1/2 mo., and I know it's best to have it done before her first heat if at all possible (if you're going to spay, that is).
I'm sure someone else will post with other panty ideas
