Don't know what to do about dog's furniture chewing

[Twiceover]

Every time I sit down in the dog starts chewing the kitchen chairs. Every time I sit in the living room, she chews the sofa. It's so wearing.
I'm happy for her to sit with me, I'm happy to give her attention, I'm happy to play with her and I try and divert her with a toy but she just goes back to chewing the furniture. So I just put her out of the to stop the chewing and we sit separately.
I don't know how to stop her destroying the furniture otherwise!
She's a 13 month old cockapoo.

just wanted to say also that i gave mine all sorts of different animal bones, trachea etc. but he was absolutely repulsed by their smell, wouldn't have them in the house and would bury them never to be seen again!
