Wow! That is a great x-ray, nice & clear. Does look like a nice size baby but she has all the room to grow, all by herself.
I'm praying for her but sure she'll do fine. Diva had 1 as you know and the vet was also saying how big the baby was. She had no problems, it was all smooth sailing with the whelping. As attentive as you are to Halle & her needs, I'm sure you will know when the time comes if she will need any help.
How exciting...1 more week to go and you'll have the great scent of puppy breath all around you! I'm sure she's gonna be beautiful!!
And I'm glad you got to talk to Dr. D for reassurance to!
