Progesterone Testing & Vaginal Cytology in Dogs

Progesterone Testing:

In dogs progesterone, a hormone produced in the ovaries, can be monitored through blood levels as a bitch advances in her heat cycle. When progesterone levels are tracked and the spike in progesterone is noted then optimum breeding dates can be determined to maximize conception rates along with projected due dates. This tracking of hormone levels and pin-pointing timing of ovulation becomes extremely important if artificial insemination is required. We offer progesterone monitoring (sent out to an external lab with results within 12-24 hours), in house vaginal cytology and artificial insemination (fresh, chilled and frozen/surgical).

Vaginal Cytology:

Vaginal cytology is performed on female dogs during their estrus cycle to help determine the optimum time to breed and enhance the success of pregnancy. The types of cells present in the vagina vary depending on the stage of estrus. A swab is taken of the cells lining wall of the vagina and analyzed under a microscope. Usually more than one swab is required to determine the optimum time to breed. Often timing of ovulation can be more accurately determined when progesterone blood levels are monitored along with vaginal cytology.  Exact timing of ovulation can aid in conception rates and give precise due dates.

***Whelping due date is calculated to be 62 days following ovulation as determined by progesterone monitoring (regardless of breeding dates!)***

If you have questions concerning your breeding program please call us at 613-624-5554 to speak with one of our veterinarians or technicians. We also advise additional tests be performed on your breeding female prior to her estrus cycle. Blood work including a thyroid analysis will rule out any potential breeding problems that may be addressed prior to the breeding period. Please call and set up an appointment if you wish to discuss your breeding program in greater detail.
