What level of progesterone indicates pregnancy in dogs?
The progesterone profiles of pregnant and nonpregnant bitches do not differ significantly; therefore, progesterone cannot be used for pregnancy diagnosis. However, progesterone levels above 2.6 ng/mL are required throughout the entire pregnancy to maintain pregnancy.
When should a dog have a progesterone blood test?
In general, we would recommend that you start testing progesterone levels between day five and seven after the start of pro-oestrus (vulval bleeding and swelling), and repeat the test every two or three days depending on the result.
What is the best progesterone level to inseminate a dog?
30-35: Some dogs still conceive with progesterone’s in this level, especially those who are still 3-6 days since they ovulated, or when the progesterone went over 6. Transcervical or Surgical insemination is best, because the cervix will be starting to Page 2 close.
How fast does progesterone drop for pregnant dog?

How much is a progesterone test for dogs at vet?
The cost of the test seems to average about $80 from the pricing we see across the country. With that cost, you are at $245 for the trip.
What is a dog’s normal progesterone level?
The beginning progesterone levels are typically less than 1.0 ng/ml until the day before the LH surge. The day of the LH spike, serum progesterone concentrations are 2-3 ng/ml; the day following the LH surge, the serum progesterone concentration is 3-4 ng/ml. Ovulation occurs at a progesterone level of 5 ng/ml.
How do you read progesterone test results?
In a menstruating female, at the beginning of the menstrual cycle, the Progesterone levels should be low then increase after ovulation and fall again.

The progesterone test can be done every 2-3 days starting about 3-5 days into the heat. Timing of the test can be more certain if the lengths of the dog’s previous heat cycles are known. The beginning progesterone levels are typically less than 1.0 ng/ml until the day before the LH surge.
What level of progesterone indicates miscarriage?
Many studies have shown that low serum progesterone is associated with threatened miscarriage. Our group has validated a single serum progesterone cutoff of 35 nmol/L taken at presentation with a threatened miscarriage can differentiate women at high or low risk of subsequent miscarriage [14, 15].
Can a pregnancy survive low progesterone?
How low progesterone affects pregnancy. We’re not sure how low progesterone affects pregnancy. Some experts say low progesterone has no impact, while others say that without adequate progesterone the uterus won’t be prepared for pregnancy and the embryo won’t be able to implant and thrive in the uterine lining.
What should progesterone be at 7 weeks?
It increases thereafter from gestation weeks 7–9 (mean serum progesterone in week 7 = 63.4 nmol/L, compared to 67.7 nmol/L in week 8 (p = 0.374) and 78.9 nmol/L in week 9 (p < 0.001).
What level of progesterone causes miscarriage?
Is low progesterone a cause of miscarriage?
Low levels of progesterone might be the first sign that the body is preparing to miscarry a pregnancy that has already failed (such as when there are chromosomal abnormalities in the embryo or fetus).
