Understanding the Dog Progesterone Levels Chart For Breeding: The Ultimate Guide!

For the dog breeding professional and the occasional breeder, timing your dog's ovulation is key to a successful litter. Once you understand your dog's ovulation level, you can time out the complete cycle of your dog. Start at the beginning by knowing your dog's ovulation levels. One of the most crucial tools for ensuring success in canine reproduction is the progesterone Levels chart that is correlated to the Progesterone machine you use for testing. This chart, when used correctly, allows breeders to pinpoint the best time to mate their dogs, maximizing the chances of a successful pregnancy, with a healthy and larger litter. The very first thing you need to know (that most people selling equipment don't tell you or they just don't know) is that every canine progesterone testing machine on the market will have its own progesterone levels chart that is accurate for that system! The facts are that all of these progesterone machines have their own ranges. That is because every system has its own bias due to the software, calibration curves, test kit formulation, and many other factors. You must use the progesterone level chart for the progesterone machine you are testing with. If not, you will not get accurate values.

What is a Dog Progesterone Level Chart?

A progesterone breeding chart is a visual tool that is correlated to the progesterone machine you are using. As you test and track the levels of progesterone in a dog’s blood throughout her estrous cycle, the progesterone level chart calibrates the testing value from your progesterone machine to tell you at what part of the dog's cycle you are at. Progesterone is a hormone that plays a vital role in preparing a female dog’s body for pregnancy. By monitoring the rise and fall of progesterone levels, breeders can determine the optimal time for breeding.

Why Dog Progesterone Levels Matter

Progesterone levels are the most reliable indicator of a dog’s fertility status. As a dog progresses through her cycle, progesterone levels change in a predictable pattern: These values are for a general example; remember to use the progesterone level chart that came with your system.

1. Low Levels (<2 ng/ml): Before ovulation, progesterone levels are low. This stage is not suitable for breeding.

2. LH Surge (2–4 ng/ml): The luteinizing hormone (LH) surge triggers ovulation. Progesterone levels begin to rise, signaling that the fertile window is opening.

3. Ovulation (5–15 ng/ml): This phase marks the release of eggs from the ovaries. Although the eggs are released, they need time to mature before they are ready to be fertilized.

4. Breeding Window (15–40 ng/ml): This is the optimal time to breed. The progesterone levels continue to rise, indicating that the eggs are mature and ready for fertilization.

5. Post-Ovulation (>40 ng/ml): Progesterone levels continue to rise, indicating that the fertile window has passed. Breeding at this stage is unlikely to result in pregnancy.

Interpreting the Dog Progesterone Level Chart

Interpreting the progesterone breeding chart can be straightforward if you understand these key phases:

1. Pre-LH Surge: During this phase, continue monitoring but do not breed. The progesterone levels are still too low.

2. LH Surge: This is the signal to prepare for breeding. Start planning for insemination or natural mating within the next few days.

3. Ovulation: Eggs are released but not yet ready for fertilization. Continue to monitor levels closely.

4. Optimal Breeding Days: These are the days to breed. The progesterone levels indicate that the eggs are mature and ready to be fertilized.

5. Post-Ovulation: If you missed breeding during the optimal window, wait for the next cycle, as the chances of conception drop significantly.

6. How to use this on your Progesterone level chart: When you get a result, print off the result that you get from the progesterone level chart that came with your system. Simply look up the result value you got on the chart, and it will tell you which level you are at from the list above. The results of your testing are very much affected by how accurately you follow the steps in running your test.

Questions About Dog Progesterone Level Charts for Breeding.

1. How often should I test progesterone levels? It’s recommended to start testing every 2–3 days as your dog approaches the middle of her cycle. Once the LH surge is detected, testing should be done daily to pinpoint ovulation and the optimal breeding days.

2. Can progesterone testing be used for both natural breeding and artificial insemination?  Yes, progesterone testing is crucial for timing both natural breeding and artificial insemination. Accurate timing improves the chances of successful conception in both methods.

3. What if the progesterone levels are high, but the dog doesn’t become pregnant? High progesterone levels indicate that ovulation has occurred, but pregnancy is not guaranteed. Other factors, such as sperm quality, timing, and the health of the reproductive organs, can affect pregnancy success.

4. How does progesterone testing differ from other fertility tests?  Progesterone testing is the most direct and reliable method for determining the best breeding time. Other tests, such as LH testing or vaginal cytology, can provide supporting information but are less precise than progesterone testing.

Anbio 100c, Cube Vet, And More!

With The  Highest Level Of Accuracy And Precision,

Along With Ongoing Support! We Have Your Back!

Here are two examples of dog progesterone level charts from CanineP4. These level timing charts are both developed from dog serum coagulation studies of 50 to 100 tests done on a Siemens Immulite 1000 or 2000, and then the system we are testing (in this case, the Anbio 100c and the Cube Vet). These tests have a range of results from high to low. Once the study is done, the levels are correlated to the Immulite analyzer to give you the very best information that is transposed to the timing charts you see below. CanineP4 and MR Diagnostic Services are the only company that does this kind of correlation to make sure your testing is accurate.
