How do you test a dog for ovulation?

When does LH surge happen in dogs?
Dogs go through a further maturation phase post ovulation so their optimum fertile period is Days 4 through Day 6 and post LH surge. Additionally, the LH surge can be less than 24 hours or as long as 48 hours, so without daily blood testing, the LH surge can be easily missed.
How do you test for LH surge?

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.
How can you tell if a female dog is fertile?
Usually the discharge decreases and becomes lighter, almost pink, in colour. The vulva becomes very enlarged and soft, and the bitch will be receptive to the male. This stage may last 3 or 4 days or as long as 7 to 11 days. The female may be receptive a day or two past the time when she would still be fertile.

What time of day is LH highest?
Ovulation is related in time to the onset of the LH surge, and occurs 40–45 h following the onset of this surge as detected in blood. The commonest time for the LH surge (as detected in blood) to commence is between 05:00 and 09:00.
Is it normal for LH to go up and down?
According to a few studies (here, here, and here), there are many different LH surge patterns: 42%-48% of cycles have a short LH surge before ovulation; 33%-44% of cycles have two LH surges (an initial big rise, small drop, then a second rise in LH); and 11%-15% of cycles have a “plateau” pattern (when levels of LH …
Does LH surge always mean ovulation?
A rise in LH levels in the blood can predict when the follicle (sac where the egg ripens) is ripe and ready for ovulation. Because LH is released in pulses or short bursts, the LH surge is not always found by a single blood or urine test.
