Some greys can't be in a crate for long outside of the track. Can I ask why you already have your grey isolated on another floor away from it's family!?
Oh i meant at bedtime we'd all be upstairs together, i was questioning the fact because they don't know stairs and if he or she was to sleep up there with us it would have to be taught.downstairs he or she would have a nice fluffy doggie bed to lounge on in the living room with us. id never isolate the dog from the family, sorry if it sounded that way.
