You can't expect an outdoor dog to be houstrained in less than a day!

Do you have a leash for her? Take Roxy outside often - especially when you wake up, after each meal, and of course, when she looks like she has to "go."

Is there a certain spot she likes outside? If so, take her there, and praise her when she "goes" outside. Or else just take her to the same place outside.

And then after give her a little run, play with her, or something she likes.

Good luck!
