Well I am glad the vet says she should be fine. I can't offer you any advice on the whelping and such, but I can offer you an ear if you need it. I hope that everything goes good and wish you a happy thriving litter!
Have fun with the new arrivals. 3 or maybe even 5 that is gonna be so fun but a lot of work to. Let me know if you just want to have some one to chat to. Good luck.
