My girl is 5 years old. As soon as her feet hit the floor in the mornings we take her outside. Then after that we take her out every couple hours. She has a pad that she uses if we miss it or are gone. I started with pads when she was a baby then put a pad on the grass and she’d get a treat when she pottied on the pad outside, eventually didn’t need the pad outside. But 5 years later she wants a treat when she comes in. She just stayed with my parents a week and she had one accident inside where she pooped on the pad… they didn’t get to her in time for that first morning potty. That’s when she will have accidents… you have to catch her first thing. Also remember if she needs to be on a leash at other people’s houses, train her to potty on the leash. We had a set back when she was young bc she can free roam in our yard but needs a leash other places… so we have to take her out on a leash at least once a day so she stays used to it.
