Hi,
Did you have the progesterone levels checked before the AI?
Or was day 11 and 13 just based on her last AI?
Normally the progesterone level is carefully followed, when an AI is done, since it's so important to
pinpoint the right day with most ripe eggs. Especially if you're useing frozen semen.
The reason I mention this, is that from your dog's behaviour, one could suspect that she didn't ovulate.
Which of course isn't the case if you've monitored the progesterone levels, since you then know for sure that she has.
As always, time will tell. Those first four/five weeks before you know if your girl is in whelp or not, seems like months, don't they ;-)
Good luck,
Karen
