give her a command to go peeing or pooing when she needs to go, like go potty or do your necessities. Don't let her in until she does it, and may be you should go along with her, 'cause my dog, needs to go with someone to go potty. When she's done praise her a lot like crazy so that she gets that she needs to do her business outside rather than inside. You could also take her out about 2 hours after she has eaten all her food, and before she goes to bed. Good luck with your potty training and i hope this advice helps you and that your dog learns to go potty outside!!
