Maybe like it's sort of reverse potty training? Is there a mat or a bit of rug she pees on occasionally? If there is, then maybe put the pee pad down there and see if she'll use it? Or bring a bit of grass or dirt right after she's peed on it and put it on the pee pad to encourage her to go where she can smell the scent? These are all questions cuz I really don't know LOL...But I must say that in the house I built we had to go through the garage to get to the door to the dog run and they did it with no problem. you could also put up a pup port like Rafi and Lisa do...it's a brilliant idea in this rotten climate!
