Mine are older - Gabby is 9 and Gage will be 2 soon. They don't wake me up unless there's an unfamiliar noise - then they bark. Gage must've heard something early this morning cause he woke me up with his barking around 3:00 and didn't stop for like 30 minutes - no matter how many times I went and told him to calm down. But most of the time, they sleep all night
