Sorry for another question.
My boyfriend and I both work overnight (11p-7a) and home during the day to sleep. I get up with her every 3.5 hours to go outside and pee. She goes and is happy to go back in her crate. We are unable to come home at night from work and she has been peeing in her crate. My boyfriend suggested we get her a playpen with just her crate and peepads for the nights we work. Will this confuse her and any progress we have made to make her pee outside?
