Scratching at door

Hello there, I have a Bernese mountain dog, female, about to be 3. We have had her since she was a pup. We originally had her at one house and then we have been in this current house for over a year. Have not had any issues and it’s been great.

Yesterday, I came home and noticed white flakes on the floor. After looking, I noticed she had scratched at the door and door frame and scratched it up bad. She’s never scratched at the doors like that, ever. We set up a camera yesterday down the hallway to monitor her and see if she does it again.

I checked the cameras today and she did it again! Like I said, we’ve been in the house for over a year, never had this issue. Nothing has changed in our schedule, in her sleep or food schedule, everything has been the same.

I am stumped on why she is all of the sudden, getting in her hind legs, and scratching to get into the bedroom. I have a feeling it’s cause she wants to lay on the bed but she has a couch upstairs and downstairs to lay on, and her dog cot, she has access to all of that and her toy, food and water bowl as well.

Anyone deal with this or might know why? I don’t know how to get her to stop damaging things and scratching. Any help would be greatly appreciated! Thanks in advance!
