🐾 Understanding Canine Progesterone Levels: A Breeder’s Guide to Timing

Accurate progesterone testing is the foundation of successful breeding. Here's how to interpret test results and use them to optimize your breeding schedule.

📊 Progesterone Ovulation & Breeding Chart

Vet Chroma Canine Progesterone Breeding Timing Chart
Optimized for Breeders 

  • 2.0 – 4.0 ng/mL – LH Surge (Day 0)
    Ovulation expected in ~48 hours.

  • 5.0 – 11.9 ng/mL – Ovulation Window
    Eggs are maturing. Not yet ready for fertilization.

  • 12.0 – 17.9 ng/mL – Day 1 Breeding
    Ovulation complete. First viable breeding day.

  • 18.0 – 24.0 ng/mL – Mid-Day 1 to Day 2 Breeding
    Ideal for fresh, chilled, or frozen semen.

🔬 Why Progesterone Testing Matters

  • Improves Conception Rates: Timed breeding based on progesterone ensures sperm meets a mature egg.

  • Avoids Missed Litters: Guessing can result in mistimed breedings and costly mistakes.

  • Supports All Breeding Methods: Fresh, chilled, or frozen – each has ideal timing based on progesterone.

  • Essential for Subfertile Males or Expensive Semen: Makes every attempt count.

📌 Breeding Method Timing Tips

  • Natural Breeding: Begin 2 days after ovulation (~8–10 ng/mL+), repeat every 48 hours.

  • Fresh-Chilled Semen: Optimal between 12–20 ng/mL, inseminate once or twice.

  • Frozen Semen: Best success after 20 ng/mL, perform surgical or transcervical AI with a vet.

🕒 Suggested Testing Schedule

Start testing around Day 5–7 of heat. Continue every 48 hours until the LH surge (~2.5–4.9 ng/mL) is detected, then switch to daily testing. Timing your breedings based on accurate progesterone data gives you the highest chances of success.
