boxer dog overdue

Question
Hi my boxer dog is overdue now for 6days and should of had her
pups on the 1 June, she feels ok and hasnt produced any milk
is this ok?

Answer
Hi Naira

Did you only breed her one day?  Was she ovulating?

The eggs take 7 days to mature, and sperm can stay viable for 72 hours.  So there is a window of error that has to be accounted for.

The alternative is, she is experiencing a false pregnancy.
