Understanding Wondfo Progesterone Levels
🧬 Canine Progesterone Interpretation Chart
(Optimized for Wondfo Pro-DX users – range: 0 to 50 ng/mL)
Progesterone Level (ng/mL)StageWhat It Means / Breeder Guidance
< 1.0Anestrus / Early ProestrusHormone levels are low. Still early. No action needed.
1.0 – 2.5Rising / Early ProestrusStart testing daily. Ovulation is not yet near, but approaching.
2.5 – 4.9LH Surge ZoneLH surge likely occurring. Ovulation expected in 48 hours.
5.0 – 8.0Ovulation ZoneOvulation likely occurring now. Breeding window begins in 1–2 days.
8.0 – 15.0Fertile WindowBegin breeding (natural, AI). High chance of successful conception.
15.0 – 25.0Peak FertilityOptimal for TCI or surgical AI. Ideal for frozen semen use.
25.0 – 35.0Late Fertile / Declining Egg ViabilityBreeding still possible. Viability starts to decline after 25–30 ng/mL.
35.0 – 40.0+Post-Fertile / Possible Missed WindowBreeding still possible. May have missed optimal window.
🩺 Note: These numbers are based on average reproductive cycles in dogs and may vary slightly by breed. Wondfo Pro-DX offers high sensitivity and fast results, making it ideal for pinpointing LH surge and timing breeding precisely.
💬 Real Breeders. Real Results.
A Game-Changer for My Program
We used to run back and forth to the vet and spend $500+ per heat cycle. Since getting the Wondfo Pro-DX, I’ve timed 4 litters in-house. It paid for itself in just two months.
Jessica R., Golden Retriever Breeder – TX
Easy, Accurate & Reliable
I’m not tech-savvy, but the Pro-DX is super easy to use. My results are consistent, and we’ve had more confirmed pregnancies since switching. It gives me total control over timing.
Marcus D., French Bulldog Kennel – FL
Classic Model Still Works Great!
I travel for AI work, and the Wondfo Classic has been my go-to for years. It’s simple and reliable. Still running strong after 300+ tests—it’s an essential part of my toolkit.
