The best I can find
I have a very small and old (16 yrs) maltese. These are the best disposable diapers that fit her good and rarely leak. I don't think you'll find disposable diapers that will never leak, you just need to make sure they are on properly.  In one diaper, she has urinated in it twice and they hold up well.  These diapers are very absorbant and don't come off easily.
