Thanks everyone! I did not realize you all had left all these comments...but to answer how I got her to ring the bell to go potty...it was pretty easy actually. I started off just teaching her to ring the bell on command. I took her paw and hit the bell to let her know what I wanted and gave her a treat every time. She was so excited, like "All I need to do to get a treat is ring this bell?!!" So once once she knew she would get a treat for ringing the bell, I would open the door every time she rang it so she would associate ringing the bell with going outside. Then I started having her ring the bell every time we would go outside to go potty. So now she will ring the bell when she wants out or whenever I say "Let's go out" or "You wanna go out?"
