Good evening everyone~ TGIF.

My Belle is about 5 mons old now and has been trained to go on the pad, although sometimes she has a tendency to forget and pee in the corner instead. When I'm at work, I leave her in a play yard in the living room with a training pad in the corner. She's pretty good with peeing and pooping on the pad. Lately she has been holding her poop in and waiting until after I walk her when I get home. Except she doesn't go outside, she waits to come back in and then she poops.

She has yet to relieve herself outside, always waiting until we're in. What can I do to start getting her to go outside?
