How Do I Know If My Dogs Cervix Has Dilated Does My Dog Need A C-section?

Does my dog need a c-section? - how do i know if my dogs cervix has dilated

My dog is 69 days after the first draw and 64 days since the last loop, my vet checked them today and said that her cervix is not extended and no puppies or near the birth canal, has been rec. We expect, if they wait for a section, instead? I do not want to lose him, or a puppy!
