What a missed-heat streak actually tells you, and when to call the vet

A single missed heat observation is common and usually not alarming on its own — detection isn't perfect, and a quiet or poorly-timed heat can slip past even careful observation. The pattern worth paying attention to is consecutive misses: two or more missed heats in a row for the same animal, counting back from the most recent observation.

A run of consecutive misses can mean a few different things, and they call for different responses. It might genuinely be a detection problem — the animal is cycling normally, but the visible signs aren't being caught, which points toward adjusting when or how often the herd is observed. Or it can point toward a reproductive health issue that's suppressing or masking normal cycling activity altogether, which detection changes alone won't fix.

This is the reasoning behind treating consecutive missed heats as one of the standard triggers for an alert, rather than treating each missed heat as an isolated, low-priority event. Two in a row for one animal is a reasonable point to take a closer look — checking body condition, reviewing recent health events, and if nothing obvious explains it, involving a vet before a third or fourth cycle goes by unaddressed.

The broader habit worth building is recording every heat check, not just the heats you catch — because a miss you didn't write down is a miss you can't see a pattern in later. A record that only shows successes will always look healthier than the herd actually is.
