Thanks for the replies guys.
We have blocked off one of the sofas, but need to find something to do the other sofa and tv.
She will gladly give you back what she has taken when you say leave, unfortunately if you try to pull her out of said hiding place she will growl at you and if you persist she will try to bite
Thats why we resorted to getting her to come when called and then treating.
We did have issues over food guarding when we got her but we have made loads of progress with that so am hoping we can get to grips with the sofa and tv sagas.
She can be a very stubborn mule when it suits her.
