Thanks everyone! We had a good night together...everyone slept til 7am then when out and did their business, no accidents.
I sleep with my dog in my bed, and Peanut is too small to jump up and down. She slept by my head all night and did really well.
I wasn't planning on another dog, but now I'm seriously considering keeping her. My youngest daughter is moving out in January and I will be by myself with Lucy. I work all day plus I have an internet jewelry business that takes up quite a bit of my time most evenings. Lucy gets impatient when I'm making jewelry at night and I'm hoping Peanut will be good company for her. Peanut seems healthy enough despite her small size. I will talk to her owner about the breeder. Thank you so much for all your advice. I will post a picture of my new baby soon
