Oh dear, not good. There could be many reasons why, if she has been off her food maybe she isn't feeling well? How long was she left for?

 

My lurcher does this and he is 13 yrs old and has always done it since we adopted him 9 yrs ago ....
Dont let her have access to your bedroom whilst you are not at home

 

Dont forget as well they go through different stages (just like children )one of mine never chewed anything until he was 2
Just a thought ...has she been neutered yet? ???

 

It would be hard to give you a reason without lots of further questions/some idea of the dynamic between you. Although i am intriuged to know if she pulled the sheets back or did she devour those too?
You've already said that you'll be keeping the bedroom door closed but you may want to think about using a frozen kong filled with peanut butter (or other such delights) as an alternative of occupying her whilst you're out.
Like to know how it goes, if neutering does resolve?

 

Good vets!

 

We had a female dog that suffered from phantom pregnancies (although not until she was 2 years old). Apart from a loss of appetite, she would nurse one toy and would also try to ‘nest’ by scratching at the floor. She always chose the same spot in one of the bedrooms and did end up making a hole in the carpet. In the end, we decided to have her spayed as it was happening after each season.
