I don't know what I would do without the pee pads.
I got Sass when she was 8 weeks old and immediately bought a doggie litter tray and put the pads in it.
After the first week she never pottied in her crate again. There were a few accidents in the house in the beginning, but now she is just doing great and she will be 18 weeks on Sunday.
I am home with her all day, but love the ease of her using the pee-pads and she wakes up at least 1 time at night and I don't have to bring her outside because she has her pee-pads inside. yay!
I can understand why some people prefer their dogs to only go outside though.
