Think this is a excellent system the only problem I have with it is it does not include a natural birth requirement.
Is this because there are not enough in the breed giving birth naturally or because it is difficult to assess the reason for a section? There are in all breeds and humans times when a section is required because of reasons other than head size or pelvic size or a combination of both so perhaps it is difficult to improve the situation and it has to remain in the hands of the breeders selecting for natural birth and hoping in time it creeps through the breed as a whole.
