I think the point is that even that they are not machines, basically they don't each have their timing.
For dogs it is close to 63 + or - 1 after ovulation.
My question really is for GSDs is it closer to 64 than 62. May be even 65 but unlikely longer.
This is why knowing ovulation time aids decisions on whelping labor.
The apparent variation is due mostly to unknown date of ovulation.

This is because the eggs had been fertilized late, say day 4 or 5 after ovulation.
eggs are fertile 2 to 4 days, often 5 days, after ovulation.

Sorry I don't agree. Just try and tell the human mamas that when they are early or late in delivery. There are MANY factors that can and do effect the whelp date, including the individual bitch and the size of the litter.
My dogs are bred the day the bitch is willing and then for the next 3-4 days. So, there is no way they are bred "late". The "flavor" of your post seems too absorbed in a "preciseness" that's not always there.

Nature has it's own ways, nothing about it is ever precise.

Articles are saying that the gestation period of dogs is 63 + or - 1 day from ovulation. I have not read the percentage outside this range, only terms like "most", "usually".
For some breeds, knowing the ovulation date is used to determine the date of planned C-section.

I forget the name of that hormone, but whelping is signaled by the pups triggering or giving that hormone. I will look up.
Nature is not always unpredictable; in this case it is fairly predictable within a range of three days.

I have heard of many GSD's giving birth on the 62nd day. An ovulation test could give you more precise answers.
Every female mammal is unique and I individual females probably have their individual cycles and gestation periods.

Good info.
My bitches last litter was 63 days.
Truth is, I don't care, makes no difference in any way to me what day it is, I guess if things were off by a week I might start wondering but still changing anything would not be possible so I'm really just glad to have the litter without complications.
