My bitch normally weighs about 4-4 1/2 lbs, dad is about 5-5 1/2 lbs. I was planning on letting nature take its course with the birth, but the closer it gets, I get a little nervous with all the c-sect talk. Maybe for peace of mind I'll take her to her vet for a look-see or an x-ray to make sure the pup(s) can be naturally born...agree?
