You have to teach her to go to the door by praising her when she goes potty outside. Take her out when she wakes up, after playtime, after eating, etc. You may have to to take her out every 30 minutes or so until she gets the idea.

Most people swear by the crate. I've never used one, but it may be the way to go for you.

Whatever you decide to do, be consistent and use lots of praise when she does what she's supposed to do. She may be lazy, but you can't be.

Good luck. She sure is a cutie!
