I'm a first time yorkie owner and we went through a similar thing with Tia...for the first couple of months she had no problem sleeping in her crate in the living room on the main floor of the house. we thought this would be best for potty training her. Randomly one night she would not stop barking. I let her out to potty (although by this point she could hold it through the night)....nothing. Check if there was a weird noise or something....nothing. After a couple of days we decided to let her sleep in her comfy bed in a corner of our bedroom, not crated. Worked like a charm! She no longer barks at night, and is now potty trained perfectly on the second floor as well as the first (except for the odd pooping issue
). Maybe Chloe wants to sleep with her pack...you!
