Winter Basics for Horse Health
A Calm, Practical Guide (with a Snow-Ready Plan)
The short version (save this)
Water first: check 2x daily (more if freezing); aim for unfrozen, palatable water.
Forage is heat: increase hay/haylage as weather bites; keep fibre available as constantly as you can.
Dry + out of wind beats “warm”: shelter, waterproof rugs (if needed), and daily fit checks.
Unrugged can be absolutely fine: if the horse is healthy, has shelter, and has plenty of forage — but monitor closely.
Move when it’s safe: turnout helps bodies and brains, but don’t gamble with ice.
Watch the quiet signs: drinking, droppings, appetite, and warmth under the rug (or coat condition if unrugged).
Have a snow plan anyway: extra buckets, extra forage, grit key areas, charge your torch.
There’s a particular kind of winter evening in the UK that makes every horse owner pause for a second.
It’s not always dramatic. Sometimes it’s just that shift in the air: the yard goes quieter, the wind gets sharper, and you can feel the temperature drop before you even look at your phone. You pull your collar up, you do that quick mental scan — water, hay, rugs, feet, gates — and you realise winter care isn’t really about one big decision.
It’s about a hundred small ones, done consistently.
And yes, when heavy snow is predicted, we tighten the plan. But good winter management isn’t snow management - it’s horse-first basics that hold up through wet, wind, freeze-thaw mud, and the odd whiteout.
What follows is the approach I come back to every year: calm, practical, and grounded in what reputable welfare organisations and veterinary guidance consistently prioritise.
Winter care is mostly about protecting the basics
A horse can cope with cold far better than they can cope with:
Dehydration
Insufficient forage
Being wet and exposed to wind
Unsafe footing
If you keep those four under control, most winters become manageable rather than miserable.
Water - the least glamorous, most important job
If there’s one winter habit worth becoming slightly obsessive about, it’s water.
In cold weather, horses may drink less (especially if water is icy), and dehydration is a known risk factor for impaction colic. That’s why so much winter advice from vets and welfare bodies circles back to the same point: keep water available, unfrozen, and appealing.
Practical ways to do that:
Check water at least twice daily (more during freezes).
If you’re on buckets, use more than one so there’s always a backup.
If it’s very cold, offering lukewarm water in the stable can encourage better intake.
Don’t rely on snow as a water source. Horses can eat it, but it’s not a consistent or efficient way to meet hydration needs.
If you’re ever unsure whether your horse is drinking enough, these indicators matter: droppings, appetite, and overall demeanour.
Forage - your horse’s internal heating system
Here’s the winter truth that gets overlooked in favour of rugs and feeds: fibre keeps horses warm.
When a horse digests forage, the fermentation process in the hindgut produces heat. That’s why reputable guidance so often recommends increasing forage as temperatures drop.
What that looks like in real life:
If your horse lives out, plan for more hay/haylage when the weather turns.
If turnout is reduced, make sure stable time comes with enough forage to keep the gut moving.
If you’re managing weight, use slow feeders rather than restricting forage too hard.
If your horse struggles to hold condition, think “forage first,” then add calories carefully and gradually (for example, fibre-based feeds). Sudden diet changes in winter are rarely your friend.
Shelter and wind - the part rugs can’t fully solve
Cold is one thing. Cold + wet + wind is another.
A horse with access to shelter (natural or man-made) can make smart choices about comfort. A horse stuck in an exposed field in driving rain can’t.
Plus, if your horse is unrugged, shelter matters even more - wind and rain can flatten the winter coat, reducing the insulating air layer that piloerection is trying to create.
So, before you get into rug weights and liner systems, ask:
Is there a windbreak (hedge, trees, shelter)?
Are there dry areas to stand?
Are gateways and tracks turning into ice rinks?
If your setup is exposed, you may find that bringing horses in earlier, or adjusting turnout windows, is kinder than simply adding more rug.
Rugging - aim for dry, not “toasty”
Rugs can be very useful tools.
The goal is usually:
Dry coat/skin
Protection from wind and rain
Comfortable temperature without sweating
A few winter rules that hold up:
Check fit daily. Winter weight changes and layered rugs can create rubs quickly.
Prioritise waterproofing and a good shoulder fit.
If your horse is clipped, older, or struggles with weight, layering can be more flexible than one heavy rug.
If your horse is naturally hardy, don’t over-rug. Sweating under a rug can chill a horse faster than being slightly cool.
A simple check: slide your hand under the rug behind the elbow/shoulder. You’re looking for warm and dry, not hot and damp.
What about unrugged horses?
This is one of those winter topics that can become highly charged with emotion — but the horse doesn’t care about the debate. They care about whether they can stay dry enough, warm enough, and well-fed enough.
Many horses in the UK do perfectly well unrugged, particularly if they are:
Healthy and in good body condition
Unclipped (or only lightly clipped)
Living with access to reliable shelter/windbreak
Getting plenty of forage (because fibre is heat)
Unrugged often works especially well for:
Native types and good-doers
Horses that run hot or are prone to sweating
Horses on winter turnout where rugs tend to slip, rub, or get soaked
A quick note on piloerection (why the winter coat “fluffs up”)
When a horse is cold, tiny muscles at the base of each hair can contract, lifting the coat — this is piloerection. That “fluffed” coat traps a layer of air close to the skin, which improves insulation.
Two practical takeaways:
Piloerection works best when the coat can stay dry and reasonably clean. A soaked coat collapses and loses much of that insulating air layer.
If you add a rug, you’re partly replacing that natural insulation system — helpful for some horses, unnecessary (or even sweaty) for others.
Where unrugged can become a problem:
Cold rain + wind with no shelter (this is the big one)
Older horses, poor-doers, or horses struggling to hold weight
Horses with limited forage access (or long periods without forage)
Horses that are clipped and expected to cope like they’re not
How to monitor an unrugged horse (practically, not guesswork):
Feel under the mane/behind the elbow: you want warm skin, not cold and tight.
Watch for shivering (a clear sign they’re cold) or a tucked-up posture.
Track weight/condition weekly — winter weight loss can sneak up.
Check they’re still relaxed and eating rather than standing miserable and withdrawn.
The Western Horse UK take? Read the horse in front of you.
This is where I lean on a Western horsemanship mindset: don’t manage your horse based on what you “should” do — manage them based on what they’re telling you.
If your horse is bright, eating, moving freely, maintaining condition, and choosing to stand out of the wind, that’s useful information.
If they’re tucked up, withdrawn, shivering, losing weight, or standing with their back to the weather looking thoroughly unimpressed — that’s also useful information.
Winter isn’t a moral test. It’s a feedback loop. Adjust the plan, reward the try (yours and theirs), and keep it simple.
If you decide to rug later in the winter, that’s fine. Think of it as adjusting the plan, not “failing” at being a hardy-horse owner.
Turnout for movement, but footing decides
Many horses do better with turnout in winter as movement supports circulation, joint comfort, digestion, and mental wellbeing. But winter also brings the UK’s classic hazard: freeze-thaw. Snow melts, refreezes, and suddenly yesterday’s “fine” track is sheet ice.
So the principle is:
Turn out when it’s safe.
Don’t gamble on ice.
If you’re stabling more than usual, plan for:
extra forage
stable enrichment
short, safe movement (only if you have secure footing)
Hooves - the snowball problem (and the mud problem)
Hoofcare in winter is a whole season of its own.
In snow, hooves can pack and form snowballs, making horses unstable.
In wet conditions, you’re managing hoof softening, thrush, and skin issues.
Practical habits:
Pick out feet more often.
Keep an eye on frogs and heels.
If snow is settling, check hooves before and after turnout.
If you’re unsure what’s appropriate for your horse (shod vs barefoot, turnout surfaces, boots), your farrier is your best partner here.
The “snow-ready” plan (even if it doesn’t snow)
Snow is the weather event that exposes weak systems usually involving water logistics, yard safety, and supply levels.
A simple plan:
Extra forage on hand
Extra buckets filled and ready
Grit/salt for gateways and stable entrances
Torch charged, spare gloves, shovel accessible
A realistic turnout/stabling plan based on footing
If you do nothing else, make it easier for Future You.
What to monitor (quietly, consistently)
Winter issues often start subtle.
Keep a closer eye on:
Water intake
Droppings (quantity and consistency)
Appetite
Warmth and dryness under the rug (or coat condition if unrugged)
Stiffness/comfort, especially in older horses
If something feels a bit off, trust that instinct and speak to your vet early. Winter problems rarely improve by waiting.
A Western horsemanship lens (because it’s useful in winter)
When the weather is messy, I come back to the same three words: clarity, comfort, confidence.
Keep routines predictable.
Ask for small, achievable things.
Reward the try.
Winter isn’t the season for perfection. It’s the season for good basics and quite frankly as horse owners - survival. Be kind to yourself too!
