Bad Pooping Habit?

I need help with my 1 1/2 year old Papillon. She is house trained, and pees on her puppy pads, but poops next to it. Now for the past few weeks she has been pooping in other rooms. I can’t seem to break her of this habit, and can’t figure out why she does this. Any advice?
Thanks

How Can I Stop My Dogs From Pooping Inside When Its Raining Outside?

I have a papillon and a mixed breed/border collie. They are trained very well to go potty outside, but everytime it rains, they go inside the house. Argggg! I hate that. How can I teach these dogs that they have to go outside, even if it means they get a little wet?
