Thank you all so much for all the advice. She chews when I put the children to bed. I have decided to crate her for the time being when I am putting them to bed.

Reading this thread I have realised I am not giving her enough mental stimulation so I will be upping that as of now. I will also be looking into gun dog training.

Thank you so much for your advice. I feel guilty moaning about her as she is now cuddled up on my feet on the sofa snoring her head off

Well, bless. Have fun with her.
