Your fur baby is still VERY young and potty training might take some time. More and more posts will have the word "patience" typed in, LOL. It should be typed in stone.
You have been given great advise.
I too like the puppy pads and any aggressive behavior ignore, stop giving her attention. Act upon the good things...She will see that nobody wants to be with her when she acts aggressive.
As mentioned, you are to be the alpha and bark loud at her too. It startles them and they usually go into a submissive posture.
They only want to please us...Good luck
