Ovulation test for dogs!

Pinpointing the fertile window through serial progesterone quantification is the clinical standard for optimizing canine conception rates and litter sizes. Relying on behavioral indicators such as male acceptance or vaginal discharge leaves breeding timing to chance, as physical symptoms often fail to correlate with internal hormonal progression. In-house progesterone testing provides quantitative numerical values that remove guesswork for both natural breedings and assisted reproductive techniques.

Canine Ovulation Timing and Progesterone Testing

The hormone progesterone begins rising from basal levels during late proestrus, coinciding with the luteinizing hormone (LH) surge. Following the LH surge, ovulation typically occurs within 48 hours as progesterone levels rise into the 4.0 to 8.0 ng/mL range, depending on the diagnostic platform used. Canine oocytes are ovulated in an immature state and require an additional 48 to 72 hours within the oviduct to complete meiosis before fertilization can take place. Serial testing every 2 to 3 days initially, and daily once levels begin rising, ensures accurate identification of peak fertility.

Pinpointing the Fertile Window for Natural and Artificial Insemination

Timing requirements vary significantly depending on the breeding method and semen preservation type. Fresh semen remains viable in the female reproductive tract for up to 5 days, allowing for a broader insemination window. In contrast, chilled extended semen maintains viability for approximately 48 hours, and frozen semen survives for only 12 to 24 hours post-thaw. Precise hormonal timing allows breeders to schedule trans-cervical inseminations (TCI) or surgical implants to coincide exactly with mature oocyte availability, maximizing puppy counts and protecting valuable genetics.

In-House Testing Accuracy and Turnaround Speed

Sending blood samples to outside reference laboratories introduces shipping transit delays and weekend turnaround gaps that can cause breeders to miss critical insemination days. Modern in-house analyzers utilize fluorescence immunoassay (FIA) or automated clinical chemistry technology to deliver laboratory-grade results in 8 to 15 minutes.
