my puppy did this when we first brought her home for the first 5 days she barked nearly all night and with her being a dachshund they are renowned for there loud bark but we just ignored her then on the sixth night she was silent all night and from then on i guess she just realised no one was gonna come and gave up she also sleeps dowstairs in our kitchen in her crate but just hang in there the barking wont last long.
