I found a good site about progesterone levels. I know my own reproductive vet, Dr. Robt. Hutchison always checked for a drop to at least a #2 or lower before performing c-sections. #5 seemed to be ideal for breeding within a 3 day window. http://www.peteducation.com/article.cfm?c=2+2109&aid=3201 I never needed a c-section before I had pembroke welsh corgis. My first girl I did a c-section because I was so afraid she would not be able to deliver. Her second litter, she had her appointment, but the hormone level was still too high. So her section was re-scheduled for the following day. She delivered naturally during the night. It was a PITA because unlike our shepherds, she would stick her behind in a corner so I could not check or see what was happening. And she did not want help. All the subsequent progeny from her needed c-sections and I liked it that way. No more bums stuck in a corner.
