Make a massive fuss of her when she goes outside, when she goes inside don’t smack or shout at her (this is interaction and a form of reward), but ignore, while you clean it up if she comes up to you just push her away with the back of your hand and don’t make eye contact. Domestic dogs crave eye contact with people, they learn very quickly it is the secret to our communication (with other dogs its mouth and tail). Depriving her of it, and not interacting with her is the most effective neg feedback for all bad behaviour you want to discourage, use it later when she start jumping up, physically turning away is also good for that.
