    I think it's different for every mare, but usually like once every 20 days or so?? Lol maybe someone can correct me. My mare usually goes into heat once every 14 days, and she stays in it for about 5 days.

    heat cycles are approximately 21 days They are in heat 3-7 days and then out for 14 days or so

    Assuming its spring and we are talking regular heat cycles

    For my mare who I would just love to have spayed, even once a year is too often. She is the definition of moody mare.

    Does anyone know why aren't mares regular all year like humans?

    It has to do with the lenght of day light influencing hormon production, and, in fact, in some regions of the world they can go all year round. I better dont try to go into detail, cause I'm sure to mix something up!

    I don't know all the details, but it definitely has to do with light. That's why people breeding for early foals often "put the mares under lights". It brings them into estrus faster.
