Progesterone Testing

In the dog, progesterone rises just prior to ovulation and remains high until just prior to whelping. For maximum fertility, it is critical to time breeding using progesterone as it helps to determine when ovulation has occurred.  Progesterone levels can vary from dog to dog, and may even vary from cycle to cycle in an individual dog. Using a progesterone assay, we can determine quickly when a dog has reached the best time for insemination.
