I've had Sweep 11 months now and she still sleeps in her closed crate in our bedroom every night. As long as she continues to crate easily, we'll keep doing it. It keeps her safe from our two cats (who sleep in our bed) and vice versa, and keeps her from trying to go downstairs in the dark, both of which give me peace of mind and a good night's sleep! But it totally depends on the dog--some don't crate well (an understatement in some cases), so you would need to use another solution like a baby gate. I also think it's very important that the dog can see you, so having its crate in the spare bedroom is not ideal when the dog's getting used to living in a home and new people. Greys are not accustomed to being alone, so at least for the initial acclimation period I'd keep the crate wherever you're sleeping. And make it a super-happy, cozy space: a blanket over it to make it den-like, treats when s/he goes in it, a comfy crate mat or stack of blankets inside. If you can find a hound that's been in a foster home (ideally one with cats), that will smooth the transition for both of you, and the foster will be able to let you know how well the dog crates. By the way, Sweep's never tried to get on our furniture, so I don't think she'd suddenly decide to join us in bed if we left her out of her crate. You may have the same experience. Congrats on your upcoming adoption!
