Have any of you tried the diapers made for human babies??? I started using those on my 9 month old pups a few weeks ago and they are working great and the best thing about it is I don't have to buy and wash those belly bands and I just throw the dirty disposable diaper in the trash when it's soiled. I bought a size 2 and my boys are about 4 to 5 lbs . I don't put it on between their legs covering their poo poo area though, I put it on side ways across their bellies like the belly bands fit. Just thought I'd share...I hated having to keep the belly bands washed and they were so expensive I thought for the good ones.
