Well our little Star had a great night. I left her in the kitchen but relented after 10 minutes and brought her upstairs with us. Our Ollie sleeps upstairs and I felt that as she came from a home where she was always with other dogs, it would be wrong to leave her on her own the first night. She settled straight away by my side of the bed. I left her out first thing this morning and she did her business. No accidents whatsoever. 
She is so adorable and her tail NEVER stops wagging. She just wants someone to play with her but Ollie is not interested. He just looks at her and walks away. She’d be great with another little dog who’d play with her. She’s going to be spayed on Wed. She is one super super little dog.
