Stress in Horses

One thing I’ve been working on lately is reducing stress in my life.  Of course this is often easier said than done but I’m a firm believer in this quote:


what happens quote


Speaking from my own experience, I think we often become stressed because of how we react to situations, including our negative thoughts about what may have occurred.   It can be a difficult habit to change, but it’s one worth working on. (By the way, yoga really helps!)

Most of us know that too much stress is just plain bad for us.  It can affect many different  things, including our heart, our muscles, our immune system, our mental health, and basically our overall well-being.

For example, a few weeks ago, I came down with the flu for perhaps only the second time ever in my entire life.  And what was going on in my life the day I got sick?  I was feeling stressed (and not remembering the aforementioned quote!)

I was trying to get my house clean because friends were coming in from out-of-state and I was also trying to get ready for the upcoming Pete Ramey workshop.  And that particular morning, my four-year-old daughter opened a big package UPS had brought and dumped the styrofoam peanuts all over the living room.  They stuck to her clothes and hair, the carpet, the furniture, and pretty much anything else with which they came in contact.

I have no one but myself to blame, but I lost it when I looked over the balcony and saw this mess. I didn’t have time to deal with it the moment and you probably know how four-year-olds are when it comes to cleaning up. . .

Not even an hour later, I felt the first signs of the flu coming on (although I didn’t know it was the flu at first).  My reaction to what had happened affected my whole body and this was likely just the window of opportunity the flu bug had been looking for.  It just marched right on in.

But the purpose of this post isn’t to talk about me getting the flu. . . What I really want to discuss is stress in horses–what causes it, how it affects them,  and most importantly, how we can make a difference.

Horses aren’t like us for the most part (thank goodness!)  They tend to live in the present moment and don’t stew and fret over situations from the past.  But they do still experience stress.

Some stress is normal and a part of everyday life for horses (such as bad weather), but much of  it is caused by us–their caretakers.  Even though we may have nothing but the best intentions for our equine friends, we often don’t allow them to live like horses and this, in turn, causes stress.

Here are a few other common causes of stress for horses:

  • Poor diet;
  • Transport;
  • Heavy exercise;
  • Showing;
  • Confinement;
  • Injury/ pain;
  • Environmental toxins; and
  • Social environment.


How Stress Affects Horses

When horses experiences stress, their cortisol levels rise.  If it’s just a short-term situation, the cortisol levels will return to normal fairly quickly.  But when it’s chronic stress, cortisol levels stay elevated, and this creates a problem and can make horses sick.

An example that is similar to my flu story is called Shipping Fever.  This is a respiratory illness that horses can develop during or right after a long trip when stress causes a suppression of the immune system.

Another very common condition brought on by chronic stress is gastric ulcers.  In fact, it’s thought to affect the majority of performance horses.  There are several reasons for this–but high-grain diets, lack of access to forage, confinement, and the stress of exercise and showing are all major factors.

Other issues that can be caused by chronic stress include:

  • colic;
  • diarrhea;
  • skin infections;
  • behavioral changes;
  • tense muscles;
  • cribbing or weaving; and
  • weight loss or gain.


Reducing Stress for Our Horses

Sometimes I feel like a broken record, but I think creating the most natural lifestyle possible is the key for healthy and non-stressed horses.  We have to think about how horses were designed to live.

Here are several ways you can help to reduce stress for your horses:

Provide continual access to forage:  If you can make any change at all for your horses, I would place a very high priority on this.  Lack of forage causes a great deal of stress for the horse! If you can’t turn your horses out on pasture, at least increase the frequency of hay feeding, or better yet, use slow feeders so they never run out of hay.  And don’t forget about night time–just because you’re asleep doesn’t mean your horse is.  They need to eat through the night as well (especially important if it’s cold outside).




Feed a forage-based diet:  You might wonder what the heck this has to do with stress, but again it goes back to providing the most natural lifestyle possible.  Horses’ digestive systems aren’t meant to digest large amounts of concentrates (grains) and doing so creates stress on the body.  I highly recommend you look into feeding more forage and less concentrates–and yes, even for performance horses. (Forage-Only Diet for Performance Horses Evaluated)

Allow horses to live with a buddy, or even better yet, a herd: Horses are herd animals and crave social interaction.  Please don’t make your horse live alone.  Having a buddy or two to live with can go a long ways for their health.   (See this post for more on the benefits of allowing horses to live as a herd.)  If a horse must be separated for some reason, make sure he can see other horses at all times.




Turnout:  I’ll just go ahead and say it.  I’m not a fan of stalling horses.  I know that many people board their horses, but please, try to find a way where they can have as much turnout time as possible.  Of course, 24/7 is best, but if this can’t be managed, then any increase in turnout time will help.

Keep a Routine:  I know this can be difficult with our hectic lifestyles, but try to feed your horses around the same time each day–especially if you feed a concentrate.   If you need to make changes, do so slowly over an extended period of time.  Our horses get used to being fed at certain times and sudden changes can create stress.


So the point of this post was to at least get you thinking.  I know that some stress is inevitable both in our own lives and also in the lives of our horses, but I think it’s so important to recognize stressors and work to reduce or eliminate them.  Our horses are worth it, aren’t they?

    Great article, Casie! We can all relate to how people stress can open the door to our physical/health issues, but we don’t often consider WHAT causes stress in our horses or even HOW to RECOGNIZE their stress because they are so patient, kind, tolerant, easygoing, forgiving, and accommodating… so we tend to brush off their feelings and assume they are happy–all rather self-delusional but “normal” thinking. Keep on writing and educating! My prayer is that more people will see natural/whole-istic horse keeping as a better way to go and traditional methods (high carb, isolation, confinement, shoes, routine chemical dewormers/vaccinations) will become the anomaly and NATURAL the norm! Thanks again for being such a super resource for info and an inspiration that we “naturalists” are not alone out there!

      Thanks, Kathy. 🙂 What you said is true. It is easy to think our horse is happy in his nice warm stall full of shavings. But we are thinking like a human, not a horse. Give horses a choice, and they would most likely rather be outdoors and with their buddies. Even if it’s 10 degrees!

  2. Eleven of my horses and 1 donkey live as a herd on 20 acres. I have one, a boarder, who is Insulin Resistant and therefore has a special diet and can not eat fresh grass. We live in Oklahoma and a square inch of soil, left alone , will grow grass in `5 minutes therefore no dry lot without pea gravel which his owner is reluctant to pay for. So poor Maxx spends most of his life in a large box stall, from which he can see ‘his’ herd as long as the horses stick close to the barn. I lung him every day and when the weather permits I ride him out on the farm. But he came to me as a cribber and he hasn’t lost the habit so I know stress is a part of his life. His diet consists of Prairie Grass hay, Triple Crown 30 %, and a ton of homeopathic immune system boosters and IR supports. I would truly like to send him back to his friends and have tried short bursts, with muzzle, but his feet heat up and he goes back to his stall. Is there anything you know of that I can do for him?

    • Casie says:

      Hi Virginia–that’s a tough one. I know there are some horses that can’t tolerate any grass at all. But I’ve also heard of IR horses, when their minerals are balanced, being able to return to some pasture. It would be interesting to have a hair analysis done on this horse I think and see what imbalances he may have.

      • In the early days..2 years ago… I sent hair off to my friend who is a homeopath but I haven’t done it recently. Thank you for the suggestion. There’s nothing like sharing a problem to find another path!

          You’re welcome. 🙂

          • Come summer/early fall I am moving me and 4 horses from north east Oklahoma to north and east of Sacramento California. I am considering buying a 32′ livestock trailer that has 4 8’x8′ compartments. That way I can put 2 horses into each compartment and still have room for the hay they are used to. It will take us at least three days to get there. Is this a good plan?

            • Casie says:

              I think it’s smart to take your hay that way there will be one less thing they have to adjust to. Just make sure to stop and get the horses out every 6-8 hours and ensure they’re drinking.

    Yep I used to be like this, everything had to be perfect, then I realized that I was missing out on whats really important! NOW I would laugh and play with my daughter with the peanuts and if the houses isnt clean enough then so what!
    I recently went on a trail ride at a “ranch” and the poor horse had ulcers, and everything you just mentioned was going on, little to no foraging and probably too many horses in a too small area AND on top of that they where breeding babies. This infuritates me to no end. I WONT be going back of course and I wish I could have just bought the whole place and turned it into a decent place for the horses and the riders. Although most of the riders are probably clueless.
