Progesterone Breeding Timing InterpreterCanine
Interpret canine progesterone levels for optimal breeding timing. Key thresholds: <1 ng/mL (basal / anestrus or early proestrus), 2–3 ng/mL (LH surge — ovulation in ~48 hours), 5–8 ng/mL (ovulation occurring), >8 ng/mL (post-ovulation breeding window, eggs maturing). Optimal breeding 2–3 days after ovulation when progesterone is 15–25 ng/mL. Used for breeding management, artificial insemination timing, ovulation detection, canine reproduction, stud dog coordination, and whelping date estimation. Common queries: 'when to breed my dog based on progesterone' or 'progesterone is 5 ng/mL should I breed' or 'canine ovulation timing'.
