I have 2 washable pet diapers that us disposable pads that I used for my 65-70 pound lab a few years back. I'm pretty sure I have a box or partial box of the disposable pads if you thought they would work, I would sell them to you for $10 as I don't need them anymore. Personally, I think the washable type are the best way to go as I can't imagine buying disposable baby diapers, cutting out the tail whole every time, and messing with all that. with two washable diapers you can use one and wash the other so they stay relatively clean. Just a thought.
