When our yorkie bichon was crated he slept pretty good, but after a while he'd sleep less and less and just whimper the entire night. We had a hard time with that because if he wimpers you don't want to react and take him out of the crate. It will just tell him "if you wimper, you will be let out of your crate."
What we found to work is placing a sheet over the crate. Usually quieted him right up for the entire night. |
