Wondfo Canine Progesterone Guide: When to Breed for Best Results
| US Units (ng/mL) | Intl. Units (nMol/L) | Milestone | Breeding Guidance |
|---|---|---|---|
| 2–5 | 6.5–15 | LH Surge Progesterone begins to rise |
Begin daily testing, prepare for ovulation |
| 6–10 | 20–30 | Ovulation Estimate Day 0 for timing |
Start ovulation-based breeding plans |
| 11–15 | 35–50 | 1st Breeding Window | Ideal for natural breeding or AI #1 |
| 15–25 | 50–80 | 2nd Breeding Window | Follow-up AI or second natural tie |
| 30–40 | 95–125 | Surgical Implant Range | Only use with high-end lab analyzers |
• Natural Tie: 2–3 Days
• AI with Fresh Semen: 3–4 Days (ensure sperm health)
• AI with Frozen Semen: 4–5 Days (verify motility)
Best Practice: Inseminate twice for optimal conception outcomes.
