Our 15 month old dog (Maltese / Yorkie mix) is pad-trained and has been gated to an area in the downstairs of our house. Prior to the last week, she was 100% at either using her pad or going outside. She recently started jumping the gate, and we decided to take it down so she would not get stuck on the other side. Now, when she comes upstairs, she is often pooping or peeing on the carpet. Any suggestions?

I am not a fan of pee pads, it tells the dogs it OK to pee inside. She is old enough to be trained to only pee/poo outside. Crate her and take her outside for a awlk 40minutes after eating. Only put food down twice a dog and walk for 30-60 minutes after each meal. Do not scold if there is an accident but praise and treats for doing it outside,lots of excitement too.
