Thanks for the answers. Can you elaborate on what the reason a first litter is more risky later in life. Does the first litter somehow pave the way for subsequent litters making them easier on the b###h.
I guess what I am curious about is why is a first litter more risky at say 8 years then at 3 years. Also using same time line, why is it that a first litters carries more risk at 8 then having say a third litter at the age of 8.
