pups tend to need to potty 30 mins after they eat (im talking number 2) so if you get her outside about that time (even a few mins earlier) she will eventually get the idea...also do you reward with treats? It works wonders! They dont need much, just a little piece of something to let them know they did a good job going potty where they need to.
If the pup has an accident in the house, show it to them, sternly say NO, and take them RIGHT outside.
I have lots more, my step dad is a trainer and my mom owns a pet sitting company

It will take a few more weeks, and a few more accidents before they fully understand
