Progesterone is baseline prior to the LH surge, begins to rise at the time of the LH surge and by time the bitch ovulates is in the
4-8 ng/ml range
and by time the bitch is in her peak fertile period the progesterone is > 20 ng/ml and often in the 30-40 ng /ml range.
When should progesterone levels be checked in dogs?
The progesterone test can be done
every 2-3 days starting about 3-5 days into the heat

Progesterone
enhances the effects of estrogen on the female’s brain to provide outward signs of estrus (“heat”)
