It's simple to call it attitude, but often it's not---these behaviors are often seen as mare moodiness, though there's usually more at play.
It's easy to call it attitude, but often it's not. These behaviors can be seen as mare moodiness, but there's usually more happening beneath the surface.
What Changes in Spring
As daylight increases, mares shift into breeding season.
This impacts the ovaries, uterus, and hormone levels. When those hormones fluctuate or fall out of balance, you may notice:
-
Irritability
-
Sensitivity when riding or grooming
-
Discomfort around the barrel or hips
-
Strong or inconsistent heat cycles
These are physical signals, not just behavior, and they can look like mare moodiness from the saddle.

It Is Not Just Hormones
Hormones depend on other systems to stay balanced, especially the liver and digestive tract. For mare health, those systems help moderate how quickly changes are felt.
If the body cannot process hormones efficiently, they can build up or shift too quickly. That is when mood and discomfort become more noticeable.
Common Signs to Watch
-
Irritability or mood swings
-
Resistance under saddle
-
Difficulty hauling
-
Sensitivity to touch
-
Inconsistent cycles
A mare that feels off is usually dealing with an internal imbalance, which may appear first as subtle equine behavior changes.
Supporting Hormone Balance Naturally
The goal is to support the body, not override it. Alongside good management, natural horse supplements and herbal blends may help the body adapt more comfortably.
Herbs can help:
-
Regulate hormone levels
-
Support the uterus and ovaries
-
Ease discomfort and tension
-
Help the body clear excess hormones
Thoughtfully selected options can complement training and veterinary guidance.

Q&A
Question: Why do mares often seem moodier or more reactive in spring?
Short answer: As daylight increases, mares transition into breeding season. This shift affects the ovaries, uterus, and hormone levels.
Variations might appear outwardly as irritability, sensitivity during riding or grooming, resistance when riding, discomfort near the barrel or hips, and irregular heat cycles. These are signs of internal changes rather than just a "bad mood."
Question: Is it just hormones, or could other systems be involved?
Short answer: It's not just hormones. Hormone balance depends on other systems---especially the liver and digestive tract---to process and clear hormones at a healthy pace. If the body can't process hormones efficiently, they may build up or shift too quickly, making mood changes and physical discomfort more noticeable.
Question: What signs suggest my mare needs extra support during spring transitions?
Short answer: Watch for recurring spring patterns like irritability or mood swings, resistance under saddle, difficulty hauling, sensitivity to touch, and strong or inconsistent cycles. If these show up year after year, it likely reflects an internal imbalance that may benefit from added support alongside veterinary guidance.
Question: How can I support hormone balance naturally?
Short answer: Aim to support the body, not override it. Alongside thoughtful daily management, natural supplements and herbal blends can help the body adapt more comfortably--supporting the uterus and ovaries, easing tension, helping regulate cycles, and aiding the clearance of excess hormones. These approaches should complement training and veterinary input.
