Can Horses Eat Peppermints? Candy, Treats and the Sugar Debate

Can horses eat peppermints? Yes: most healthy adult horses can have one or two plain peppermints as an occasional treat, but horses with metabolic problems, a laminitis history or a choke risk should skip them. The question has been all over X this September, thanks to a run of "IS THIS A SWEET TREAT?" horse videos. One account's September 10 clip of a horse lighting up for a peppermint passed 3,400 likes, and a September 14 poll pitting a peppermint-loving horse against a caramel-loving donkey drew more than 1,700.

In between, on September 11, the same account pushed back on messages claiming a tiny candy could hurt an 1,100-pound horse. The replies split fast: mint fans on one side, owners who limit sugar for metabolic horses on the other. Both camps have a point, and which one is right depends on the horse in front of you.

Can horses eat peppermints? Yes, with a few big exceptions

For most healthy adult horses, one or two plain peppermint candies as an occasional treat is fine. The exceptions are horses with metabolic problems or a history of laminitis, horses at risk of choke, and overweight horses, which are better off with a low-sugar reward or none at all.

Vets and nutritionists land in the same place. PetMD's veterinary guidance says one or two small peppermints is fine for most horses, Penn State Extension suggests one to two pieces of any treat, and Mad Barn's vet-reviewed treat guide calls peppermint candies and candy canes safe in moderation.

Skip the mints entirely if your horse:

• Has equine metabolic syndrome (EMS), insulin dysregulation or PPID (often called Cushing's)
• Has ever had laminitis, or carries extra weight with a cresty neck
• Has dental problems, is a senior with worn teeth, or has choked before
• Is on a vet-directed low-sugar diet for a condition such as PSSM (a muscle disorder) or gastric ulcers

The sugar math: is one mint a big deal for an 1,100-lb horse?

For a healthy horse, not really. Equine nutritionist Clair Thunes, PhD, ran the numbers in The Horse: a 1,200-pound horse eating hay with 10% non-structural carbohydrates (NSC, meaning sugars and starch) takes in roughly 1,090 grams of NSC a day.

So the viral math holds up: a couple of mints is a rounding error in a healthy horse's day. Two details still matter.

Candy sugar hits faster. Thunes notes that sugar from treats like sugar cubes dissolves quickly and moves with the faster liquid part of the gut contents, so it may be more likely to spike blood sugar than the NSC in hay. A horse with normal insulin handles that easily; a horse with insulin dysregulation is exactly the one that shouldn't get a quick sugar spike.

Habits add up. One mint after a ride is a treat. A pocketful every time someone walks past the stall is a diet change, and it teaches a horse to mug people for food.

Why metabolic and laminitis-prone horses should skip sugar

Equine metabolic syndrome is built around insulin dysregulation: the horse's body answers sugar and starch with too much insulin. According to the Merck Veterinary Manual, that high insulin drives most laminitis, with insulin-associated cases making up roughly 90% of laminitis in horses.

Some horses are more at risk. Merck lists ponies, Saddlebreds, Tennessee Walking Horses, Paso Finos, Morgans and Mustangs as most commonly affected, notes that donkeys get it too, and says it usually shows up between ages 5 and 16. Not every EMS horse looks fat, either: a lean type exists, so blood tests are how vets confirm it.

Here's the telling detail. One standard way vets check for insulin dysregulation is an oral sugar test, a measured dose of corn syrup followed by a blood insulin reading. For horses with EMS, lean or obese, Merck's guidance is to eliminate grazing, grain and treats and feed tested low-NSC hay instead.

Timing matters right now. Merck notes that laminitis bouts often appear in spring and in autumn, when nights drop below freezing.

Call your vet right away if you see

• Short, stiff steps or reluctance to walk, especially on hard ground
• Shifting weight between feet, or standing rocked back on the heels
• Hooves that feel warmer than usual

Low-sugar rewards if your vet says yes

If your vet approves any reward at all, The Horse's advice for laminitic horses points to low-sugar options such as a piece of celery, a strawberry, apple peel or commercial treats labeled for insulin-resistant horses. Another option is to set aside a handful of the horse's own tested hay or hay pellets, so rewards come out of the diet it already eats.

What can horses eat? Safe horse treats vs foods to avoid

Horses are built to eat forage all day, so every treat is extra. Keep treats to one or two small pieces at a time, and cut hard foods like apples and carrots into thumbnail-sized bits, the size Mad Barn recommends for horses of any age. Our nutrition guide covers the rest of the diet.

One banana caveat: they're high in potassium, so Mad Barn says to skip them for horses with HYPP, a genetic muscle condition seen in some Quarter Horse lines.

Never feed these

• Chocolate, coffee, tea and cocoa: they contain methylxanthines such as theobromine and caffeine, which in large amounts can cause heavy sweating, muscle tremors and heart rhythm problems.
• Avocado: the fruit, pit and leaves contain toxins that affect the heart.
• Onions, garlic and leeks: linked to anemia in horses.
• Potatoes, tomatoes and other nightshades: Penn State Extension flags the nightshade family as toxic to horses.
• Lawn, hedge and garden clippings: they ferment fast and make gas, and horses can't burp or vomit to release it.
• Cabbage, broccoli, cauliflower and other brassicas: gas and colic risk.
• Milk, cheese and yogurt: adult horses no longer produce much lactase, so dairy can upset the gut.
• Anything moldy or spoiled.

Can horses eat candy? The fine print

• Plain peppermints only. No chocolate-coated mints and no mint-flavored gum.
• Skip sugar-free candy. Much of it is sweetened with xylitol. PetMD notes horses have shown some sensitivity to it, and The Horse advises avoiding xylitol-sweetened products.
• Unwrap everything, and keep Halloween buckets and candy bowls out of reach of curious lips.
• Gulpers and seniors do better with soft mints, broken pieces or a mint-flavored horse treat than a whole hard candy.

How to hand-feed a horse safely

Treats make great rewards, but a horse that learns "hands mean food" can start nipping. Penn State Extension's advice is the classic one: open your hand wide and flat and set the treat in the center of your palm, which lowers the risk of nipped fingers. Offer it calmly, so the horse learns to wait instead of lunging for it.

1. Ask first. Never feed someone else's horse, at a lesson barn, fair or roadside fence, without the owner's OK. That horse may be on a strict diet.
2. Flat palm, fingers together, thumb tucked in.
3. Small pieces only. Thumbnail-sized, and break hard candy for older horses.
4. No crowds. Don't pass treats over a fence to a group of loose horses; competing for food can lead to kicks and bites.
5. Reward manners, not mugging. Treat a horse for standing politely or turning its head away, never for pushing into your pockets. Positive-reinforcement methods like clicker training build this habit well.
6. Kids watch first. An adult demonstrates, and if the horse is pushy, the treat goes in a bucket instead. Our safety guide covers where to stand.

Know the signs of choke

Choke in horses is a blockage of the esophagus (the food tube), not the windpipe, so the horse can usually still breathe. The Merck Veterinary Manual says the classic sign is food coming back out through the nostrils, often with heavy drooling, coughing and an anxious horse stretching or arching its neck.

If you see it, remove all food and water and call your vet. Don't try to clear it yourself: the longer a blockage stays, the higher the risk of complications such as aspiration pneumonia.

Why horses love peppermint (and what the cayenne fence taught us)

Horses have real flavor preferences. Flavor research cited by Mad Barn lists peppermint alongside fenugreek, banana, cherry, carrot and oregano as tastes horses tend to enjoy.

Preferences are personal, which is what makes the "treat personality" videos fun: one horse goes wild for a mint while the donkey next door holds out for caramel. Reactions like these are a window into horse behavior.

Tastes can backfire, too. A September 19 post described brushing cayenne paste on a fence to stop a horse from chewing it, only for the horse to enjoy the spice.

If you compete under FEI rules, note that capsaicin, the hot compound in chili peppers, is listed as a banned substance on the FEI's 2026 Equine Prohibited Substances List, so hot-pepper products don't belong around competition horses. Fence chewing often means a horse wants more forage or more to do, so extra hay time usually beats hot sauce.

What to do next: a fall and holiday treat checklist

Halloween candy and December candy canes are coming, and fall pasture is already a higher-risk time for laminitis. Before you share a sweet:

• Is this horse healthy, at a good weight and not on a special diet? If you're not sure, ask the owner or the vet.
• Is it a plain peppermint, unwrapped, with no chocolate or xylitol?
• Is it one or two pieces, small enough to chew?
• Is your hand flat, the horse calm and no herd crowding in?
• Metabolic, laminitic or senior horse? Swap in celery, a few hay pellets or a good scratch on the withers.

What to watch next: as horses put on winter weight, look for a thickening crest or fat pads near the tailhead. If you see them, ask your vet about insulin testing before the holiday treat season.
