Zoe is 6 months old and usually goes outside however, that is because I take her out frequently and when I am not here, she is in her crate. She doesn't ask to be let out and I want to do away with peepee pads if I can. She uses those pretty well if I don't get her out at the right time. She never asks to go outside to potty. I'm wondering if anyone has used the doggy diaper as a training aid and if it has worked at all? Thanks for any help!
