I'm trying to training Desi to do both. Right now, she is pretty well trained on the wee pad, which I like because if we go out for the day, I'm not worried about running home to walk her. But, I would like her to pee outside when we are out. Right now, she will hold it until we get home and she can go on the pad. I've even tried bringing a pad with me and placing it on the grass, but she won't go..
