"She's just being mareish" isn't always the answer.

If you can't predict when your mare is in heat, you can't plan around it. Lessons get cancelled. Shows get awkward. And you spend a lot of time wondering whether the behavior is hormonal or something else.

Cycle tracking with smart predictions

Predicted estrus window

Log each heat as it happens. Proper Strides learns her pattern and predicts the next window — usually within a day or two.

Behavior observations

Tag the signs you see — winking, tail raising, mare-ish behavior, restlessness, grooming sensitivity, distraction. Patterns emerge over time.

Equibot insights

Equibot reads your observations and surfaces patterns — like which behaviors most reliably predict her next cycle.

Frequently asked questions

How long is a normal mare cycle?

The typical mare estrous cycle is 21 days — about 5 to 7 days in heat (estrus) followed by 14 to 16 days out of heat (diestrus). Cycle length varies between individual mares and across seasons.

What's the difference between estrus and diestrus?

Estrus is the phase when the mare is receptive to a stallion and her ovary is preparing to ovulate. Diestrus is the phase between heat cycles when she's not receptive. Most behavioral signs occur during estrus.

How accurate is Proper Strides' cycle prediction?

The more cycles you log, the more accurate the prediction. Most mares fall into a reliable 21-day pattern within 2 to 3 logged cycles, and confidence improves as your data grows.

Can I track multiple mares?

Yes. Each mare has her own cycle record. Predictions are calculated per-mare based on her individual history, not a generic average.

What behavioral signs should I log?

Common estrus signs are winking, tail raising, frequent urination, mare-ish behavior toward geldings or other horses, restlessness, increased grooming sensitivity, and distraction during work. Log what you observe and patterns will emerge.
