ZoE's the opposite. She was only pad trained and didn't even go potty outside until she 11months old, when we were outside late one evening and she really, really had to go. She squatted & peed and stared at me the whole time..like...am I going to get in trouble for this? I told her good girl & gave her a treat.
Since then, she will go outside if she needs to, which is great for when we are traveling, as I can stop at a reststop & let her go potty. Prior to that I was putting a potty pad down in the trunk of my car when I stopped and telling her to go on that ...and she did! (both my kids go to college on the other side of the state, so ZoE & I travel a lot).
Does she have the run of the house while you are gone? If so, and she is able to get to the door you let her out to go potty, I'd put a pee pad there. I know it's kind of icky, but if you take a potty pad out with you when she goes pee, and quickly dap some up with the potty pad, it will have her scent on it, and she's more likely to go on it inside.
Or you could put her in a small room of your house or a playpen while you are gone and place her bed at one end & potty pads at the other.
