I use the disposable. I have heard some people say that when they put the washable ones down, the dogs think they can pee on the carpet. I get mine from Drsfostersmith. I was buying the xtra piddle pads, but, they're changing(they were the best by far). I will have to go with their biodegradeable ones again, which they're good too. Have also heard petedge has good ones, but, I haven't tried them yet. I just know with 4 little ones using them, the xtra's I would only have to change out a couple times a day, compared to about 6-7 times a day with the cheaper ones |
