My 9 Month Greyhound Is Crate Trained Want To Get Her Out Of It So That She Can Join A New Dog We Are Getting?

My greyhound is crate-trained in that she goes in there when I am out (once or twice a week) for 3 hours and is clean. She sleeps by my bed during the night – which we are happy with. We are getting a new dog (a 10 month old greyhoundxgerman shepherd lurcher) in 2 weeks for company for her as she has slight seperation anxiety, although she does settle down in her cage usually – although neighbours said they heard howling the other day. Apparantly, the new dog does not require a crate.
Three issues
1. how do I get her out of the crate? – she is a bit chewy.
2. how do I settle the new dog in?
3. how do I ensure that they get on, particularly when left?
Thanks
