My name is Bama!

I have a one-year-old dog named Bama she is a Rottweiler. I got Bama from my mother because she was moving to a new home and couldn't have a big dog in the home so we took Bama in. Bama is good with kids she listen when you tell her to sit stop etc . Bama is a little wild when taking her outside because she be so excited. Bama is good with kids the only other problem we're having with Bama is when she was with my mother my mother had her in the house the majority of the time and she was actually pooping in the house so we're trying to potty train her to go outside we take her outside even take her in the backyard and leave her out there for a while to see if she's going to go but Bama will not poop outside. When she comes in the house she poops. So we're really looking for someone that has more time to train her.
