Sleep regression at 2.5 years

My dog is a female golden retriever (spayed), 2.5 years old. Over the past month her sleep schedule has regressed. She sleeps on her bed in our room, as she has since she was 7 months old. Up until a month ago, she’d sleep until whenever our alarms go off for work (and on weekends normally wake up around that time for breakfast).

Recently she’s been waking up at least an hour before alarms go off, and being a terror from that point forward. Jumping on and off the bed, crying, pawing. The people who live in the unit above us are up and making noise around that time, but it’s never been a problem for her until a month ago. We don’t reward her or acknowledge her when she wakes up this early, but it hasn’t make much of a difference. Everything else about her schedule is the same.

Any advice? We’re all getting at least an hour less of sleep a night, and honestly, it’s super frustrating. Any advice?
