Has anyone had success housetraining a puppy using outside as the primary potty spot [View all]

and then using some sort of potty space (pee pad with tray on deck or in the garage) without encouraging in-home accidents or thwarting success?

We're picking up our dog in a week, who is about 4 months, and will be potty training outside, but I'd love to have the option of having her use something more sheltered in case of bad weather.

Thanks!
