Dog chewing bed

Hi! My dog is chewing through her beds and I’m not sure what to do. She is a 10 month old lab, we have a large crate for her. She stays in her crate when we are at work and at night. But lately she has started chewing her beds. She has went through 2 in the past few days and im getting really frustrated.
Any tips on what to do? Should I try bitter spray? And if so, what kind do you recommend?
Also, I’d like to be able to not have to have her in a crate. My other dogs do fine with no crate, should I just leave her out one day when im at work and see how she does?
