What LH level indicates ovulation in dogs?
The ideal time for timing is to get a baseline line level prior to the LH surge, one around the time of the surge and and continuing to monitor until ovulation is confirmed with a level > 5-8 ng/ml.
What is the LH surge in female dogs?
The LH surge is the hormonal event that results in ovulation. The LH surge occurs 48 – 72 hours prior to ovulation and it lasts for 12 – 24 hours. Because the LH surge is so short, it requires daily blood sampling.
What progesterone level is too late to breed a dog?
After ovulation and breeding are completed, the progesterone level will continue to rise. The level typically rises to 40 to 50 ng/ml (the normal range can be 10 to 90) whether the bitch is bred, pregnant, or not.
How fast does progesterone drop before whelping?
About 48 hours
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.
What progesterone level indicates labor in dogs?
Dogs typically enter stage I labor within 24 hours of a decline in serum progesterone to <2 ng/mL, which develops in conjunction with increased circulating prostaglandins and is commonly associated with a transient drop in body temperature (<99°F [37.2°C]).
What is the best day to breed a dog in heat?
tenth and fourteenth day
For most females, the best time for breeding is between the tenth and fourteenth day of estrus. However, some females ovulate as early as the third or fourth day or as late as the eighteenth day.
What nmol should I breed my dog?
between 30-65 nmol/L
Optimal fertility is between 30-65 nmol/L at the time of breeding.
What progesterone level indicates labor?
If progesterone is below 2.8 ng/mL, there is a 99% probability of whelp within 48 hours, and if the level is below 1.0 ng/mL this probability is 100%. Conversely, if the progesterone is 5 ng/mL or above, the probability of onset of spontaneous parturition within the following 12 hours is less than 2%.
How many times should you ai a dog?
Ovulation generally occurs at the end of or just after standing heat. She is most fertile from four days before and three days after ovulation. That is the window we are trying to hit with our AI breeding. This is why we recommend to AI the female every other day to try to time it with her estrus.

The discharge can range in color from deep red to milky pink or white. The dog will typically be fertile about 12 days after the bleeding slows and gets thinner and lighter.
When should you inseminate after LH surge?
