Hi, I'm new here, just rescued Bella. She's seven months old and my first small dog

. She was abused by her previous owner and I'm the fifth place she's been. We have fallen in love, she's been quite easy. We are just over two weeks in and she has just started to pee in the house without barking to let us take her out. The only problem we had been working on is her around other people, she gets nervous and bites new people. Any suggestions would be greatly appreciated!
