Joey's belly bands are just a rectangular strip with Velcro on the ends to fasten it. You put a sanitary pad in it, so is should be larger than that. I've never had any problems with leakage, and they are mainly a way to tie the sanitary pad to the dog. They would be pretty easy to make, especially if you already have some cute fabric. Several of our members make some really cute ones. Sometimes they call them wee wraps.
