Hiya
congrats on getting your new puppy soon.
The best advice I was given years ago by a behaviourist at crufts was to introduce them outside the premises let them sniff each other and then let the older dog enter the house first as if inviting pup into her home.
We have always followed this rule and never had any problem.
we have crates as beds in the kitchen for our girls when the pup (now 8m) first came home we crate trained her.One side of the crate was a nice comfy bed (vetbed ) and a training pad on the other side just in case then cover with a blanket to make it den like ....she slept in the same room as our other girl only pup in her crate ,she slept in her crate for 3-4 nights and then we left the door open but she chose to sleep in thier herself gradually moving on after a couple of days to using our older girl as her pillow!!!!
hope this helps...
