Frequently Asked Questions

Firstly it is important not to confuse serum level progesterone testing with “pre-mate” or other off the shelf test kits, which can be affected by the temperature, the freshness of the kit or even staff’s opinion on a colour. K9 Progesterone Uk recommend accurate serum level progesterone testing your vet can take the required amount of blood sample on your behalf. 

Bitch progesterone measurement is a vital part of breeding management. It allows us to time ovulation and hence the optimum time for natural mating or insemination.

Can Progesterone level determine whelping?

About 48 hours before whelping, the progesterone level drops to the 2 ng/ml range and within about 24 hours of whelping, the level drops to the 1 ng/ml range. This can help determine the proper timing of a c-section, especially if the progesterone level or LH level were not used to determine the ovulation date. By correctly determining the whelping time, it can prevent puppies from being taken by c-section too early and thereby decreasing their chance of survival.
