Hi and welcome to YT. So glad you could join us. Looks like you may be a grandma soon.

I just hope there will be no complications. Just go ahead and make up a whelping box for her to get used to. Usually the day of birth, the mom is very restless and pants a lot. Sometimes not eating, but drinking a lot of water. This is the time to keep a very close eye on her. Don't let her outside unless your with her, and make sure she can't get under anything outside where you couldn't reach her. If you do, then put her harness and leash on each time you take her out. Good luck, and keep us up on things.
