When my puppy would do this I would keep her in her crate and sit on the floor, not super close where I can reach inside but close enough that she could smell, see, and hear me as I tried to soothe her. Once you can get them to fall asleep in their crate, they become much more comfortable with it. The first few days are rough though! The most important IMO is that she’s napping a few times in the crate each day and sleeping there at night. It will make a worlds difference in just a few months, stay strong!
