What should my dogs progesterone levels be when in heat?

Progesterone levels should be tested every two to three days once the dog is three to five days into heat. Progesterone levels are usually less than 1.0 ng/ml before the LH spike, rising to 3 to 4 ng/ml the day following the LH spike. When the progesterone level rises to 5 ng/ml, ovulation occurs.

What happens to progesterone levels after ovulation in animals?

From then on a gradual decline takes place with basal levels around 60-70 days after ovulation. Non-pregnant animals tend to have a slightly longer luteal phase than pregnant animals. The drop in progesterone will induce a rise in prolactin, which will stimulate milk production.

(Canine) Progesterone can also be used to confirm that ovulation did take place- levels over 15.0 ng/ml can be used retrospectively to confirm ovulation, but does not help in future planning of a breeding of that cycle. Progesterone can also be used to estimate the date of whelping.
