What I Actually Do When a Horse Won’t Settle Down

Last updated: August 10, 2026

My niece’s horse gets anxious every time she hauls him, and by the time they reach the show grounds, he’s washed out and soaked in sweat. I’ve seen that same pattern in racehorses and pleasure horses alike: the answer is finding the trigger, not waiting for the horse to “get over it.”

Horses are prey animals – spooking and anxiety are built into how they’re wired, not a training failure. I’ve dealt with my share of anxious horses over the years, and here is how I recognize real anxiety, what’s actually worked, and where I’ve been wrong before.

How I Know When a Horse Is Truly Anxious

The first thing I look for isn’t the behavior – it’s the physical signs. A horse usually tells you it’s anxious before it ever acts out: sweating without exertion, an elevated heart rate, faster breathing, flared nostrils, or trembling. Catching those signs early can be the difference between a manageable situation and one that gets away from you. Left unaddressed, chronic anxiety can eventually turn into destructive habits like cribbing, weaving, or pacing.

I’ve seen this play out with our own racehorses more than once. We had a filly who was completely relaxed in morning works – sharp, focused, and nothing bothered her. The moment she got in front of a race-day crowd, she’d wash out, sweating heavily and unable to perform anywhere near the horse she was in training. Another talented horse in our barn dealt with his nerves by kicking the stall walls. He eventually kicked hard enough to severely injure his fetlock joint, ending his racing career. That’s the real cost of unmanaged anxiety – not just a bad day, but sometimes a permanent setback.

I’ve had horses spook at a plastic bag and others that never blink at a bag but come completely undone around a set of clippers. That’s why I don’t look for a “nervous horse personality” as much as I look for the specific thing causing the reaction. Once you understand the trigger, you can start addressing it through desensitization, better management, and a consistent routine.

Common Triggers for Horse Anxiety

Knowing what actually sets a horse off matters more than any generic calming trick. The same triggers come up again and again.

Before You Try to “Fix” the Horse, Check These Things

The most common trigger for anxiety is a change in routine or environment – not a personality problem. If your horse is anxious regularly rather than occasionally, look at what’s actually changed before assuming you need a training fix.

Turn your horse out regularly

Horses stuck in a stall all day build stress with nowhere to release it. A young racehorse of ours wasn’t coping well with race-day pressure, so we backed off and turned her out in a pasture rather than pushing through it – we plan to try her again once she’s more mature. Regular turnout and time with other horses genuinely lowers baseline stress for most horses.

Keep your horse occupied

Stall toys, salt blocks, and slow-feed hay nets help when a horse has to be confined longer than usual – whether that’s travel or vet-ordered stall rest. We keep music playing in our barn, and our barn cats and a goat wander freely among the horses. Having other animals around gives a horse something to focus on besides its own nerves.

The First Thing I Do With a Nervous Horse on the Ground

Before handling a nervous horse on the ground, be ready for sudden, unpredictable movement. Let the horse smell you or touch it lightly before leading it anywhere. Staying calm yourself matters just as much as anything you do with the horse – horses are highly sensitive to a handler’s body language, energy, and reactions, and bringing nervous energy into a tense moment is a good way to get hurt.

If you know a horse runs nervous, work it in a controlled space – a round pen, arena, or paddock. Working an anxious horse on a lunge line in a round pen is one of the more reliable ways to settle it, since the smaller, controlled space makes it easier to redirect attention and work through the trigger safely. An open pasture works too, though a loose horse is harder to catch out there.

Calming a Horse While Riding

Know the horse you’re about to ride before you get on. Watch how it’s moving, carrying itself, and reacting to its surroundings. That tells you a lot about whether the horse is mentally ready for what you’re asking that day. This matters most in the moments where a horse can’t afford to lose focus – the post parade, the walk to the gate, or a young horse’s first workout alongside company.

When a horse starts getting anxious under saddle, my first response is to get quieter, not louder. Horses pick up on tension in a rider, and reacting to the horse’s fear often adds to it. A steady seat, calm breathing, and clear direction give the horse something confident to follow instead of another reason to worry.

Talking to your horse in a calm voice can help too. They may not understand the words, but they learn the tone and the person behind it over time. One of our exercise riders, Tammy, takes that to another level. She talks to every horse she rides the entire time. I’ll hear her out on the track having what sounds like a full conversation: “Are you ready to go?” “Easy now, slow down.” It always makes me smile, but there is something to it. She stays relaxed, her cues stay consistent, and the horses know her voice well enough to trust it. Her voice becomes part of the communication, just like the cues she gives with her hands and legs.

When Pain Is the Real Problem

Not all anxiety is behavioral. Sometimes a horse looks nervous because something hurts, and if you miss that, no amount of calming work will fix it. When behavior changes suddenly or keeps getting worse, rule out pain first, not last.

I’ve had horses that seemed hot or difficult, only to find the real issue was saddle fit or an early hoof problem. Once the pain was addressed, the behavior changed completely. Get chronic discomfort checked by a vet, especially with a high-performance horse like a racing Thoroughbred, where physical pain can look a lot like behavioral anxiety.

Do Calming Supplements Work?

I don’t recommend reaching for a supplement before you understand why your horse is anxious. A calming product may take the edge off, but it won’t fix a management problem, pain, fear, or a training issue. Used as a first response, it can mask the real problem instead of solving it.

That said, we’ve used calming supplements with some horses and found they can help in certain situations. Results vary widely, and they work best as a supporting tool alongside good management, turnout, routine, and proper training. Some ingredients, including alpha-casozepine and magnesium, have research behind them, though the evidence is not equally strong.

If you’re considering a calming supplement, I break down the ingredients, what the research actually says, and what we’ve used with our horses in my guide to horse calming supplements.

The biggest mistake is expecting a supplement to create a calm horse by itself. A relaxed horse is usually built through consistent handling, a comfortable environment, and finding the reason behind the anxiety in the first place.

Prescription Sedatives: What Owners Should Know

Prescription sedatives such as Acepromazine or Dormosedan have a place in horse care, but they’re not a fix for anxiety. We’ve used Ace on one of our own horses – a filly who can be difficult to handle on the ground but settles once you’re on her back – and it helps, but only when used under veterinary guidance. A sedated horse can still react if frightened and may not coordinate normally, which is why these medications require careful use.

There are situations where medication is what allows a professional to safely work. I’ve known farriers who won’t shoe certain high-strung racehorses without veterinary-approved sedation, including horses that become dangerous during handling. In those cases, the medication isn’t making the horse “good” – it’s helping create a safer situation while the underlying management issues are addressed.

If a horse is unsafe to handle, your veterinarian can help determine whether medication is appropriate and what else needs to change. For more on how these medications work and when they’re used, see my guide to Ace and Dormosedan for horses.

Calming a Nervous Pony

The same basic principles apply to ponies: find the trigger, rule out pain, keep the routine consistent, and build confidence gradually. What’s different is the safety situation. Ponies are often handled by kids and less experienced riders, so a nervous pony isn’t simply a smaller version of a nervous-horse problem. A pony that startles with a child in the saddle, or with a nervous child leading it, can create a dangerous situation quickly because the person handling it may not yet know how to read the early warning signs.

That’s why reliable groundwork and gradual desensitization are especially important with a nervous pony. Before putting a child on one or handing it to an inexperienced leader, make sure the pony is calm, consistent, and comfortable with the situations it will face. The goal is for that young handler to meet the dependable version of the pony – not the anxious one.

FAQs: How to Calm a Stressed Horse

Patience Beats a Quick Fix

Horses are prey animals with real, hardwired defense mechanisms built to keep them safe. Working with that instinct instead of against it is what actually works – consistency and patience, not a shortcut. Keep working with your horse until it feels genuinely confident, and bring in a professional if you’re not making progress on your own. Most anxious horses get there with time.

A calm horse isn’t born, and it isn’t sedated into existence either – it’s built one consistent, patient interaction at a time.
