@eeeefarm our room is very warm. We made sure of that since we knew they do not like being cold . She was in our room last night and still cried but did not scream like she was doing before. So that is progress, but we took her out to pee a lot (4 times).
That is progress. I think together you'll figure it out. I wouldn't worry about the temperature so much. If there is a nice blanket in there she should be fine. Basenjis like to be cozy but some also like to be on the cool side. Heated doggie pads also work if you're worried.
Having them sleep on the bed is a great idea if you're willing to have it continue. But if you start letting them on the bed you are going to have an incredibly hard time convincing them they can't later on.
Just keep in mind that this is a huge change for her. All her life she's been with her litter, always having companions and sleeping in dog piles. Now suddenly this is all gone and she's alone. So a little crying isn't a cause for concern. It's not an easy transition, which is why I don't understand why people want a pup at eight weeks.
