Can Horses Eat Grapes? A Senior Horse Guide
Can horses eat grapes? Yes, in small amounts. Grapes are not known to be toxic to horses, unlike dogs, but they are sugary and best limited for PPID and EMS seniors.
Yes, horses can eat grapes in small amounts, and unlike dogs, grapes are not known to be toxic to horses. Most horses enjoy a few as a treat. The real catch is sugar: grapes are sweet, so they should be limited, and avoided as a regular treat for senior horses with PPID, EMS, or insulin dysregulation. Choose seedless grapes, feed only a few at a time, and keep them a rare extra.
Grapes cause understandable worry because they are famously dangerous for dogs. For horses, the picture is different: there is no established toxicity, and small amounts are routinely fed without trouble. Equine research is limited, though, so a measured, moderate approach is sensible.

Grapes and Horses: What We Know
The toxicity that makes grapes and raisins dangerous for dogs has not been shown in horses, and horses are commonly fed a few grapes as a treat without ill effect. There is no equine equivalent of the canine warning. At the same time, grapes have not been studied extensively in horses, so the responsible stance is moderation: feed small amounts, watch your horse, and do not turn grapes into a staple.
How to Feed Grapes
Choose washed, seedless grapes and offer just a few at a time, by hand or in a feed tub. For an older horse with poor teeth, you can halve the grapes to be safe. Feed only fresh grapes, never moldy or fermenting ones. Because they are small and easy to hand over by the handful, the main discipline is simply keeping the number low.
Risks to Watch For
- Sugar: grapes are sweet, so they add up and are risky for metabolic horses.
- Overfeeding: their small size makes it easy to give too many at once.
- Raisins: dried grapes are even more concentrated in sugar.
The Senior Horse Note
The sugar in grapes is the reason to be careful with a senior. PPID and EMS are common in older horses, and for an insulin-dysregulated horse, sweet treats like grapes feed into the metabolic problems that drive laminitis. If your senior is metabolic, diagnosed or untested, skip grapes as a regular treat and use a low-sugar option instead.
Dental health is less of an issue with grapes than with firm fruit, since they are small and soft, but a senior that bolts a handful could still struggle. Halving grapes and feeding only a few at a time keeps even a horse with poor teeth comfortable. As always, introduce any new treat gradually and watch how your old horse handles it.
The Bottom Line
Grapes are safe for horses in small amounts and are not known to be toxic to them, unlike dogs, but they are sugary and should be limited, and avoided as a routine treat for metabolic seniors. Feed a few washed, seedless grapes at a time, skip raisins, and reach for low-sugar treats for a horse with PPID or EMS, guided by your veterinarian.

Frequently Asked Questions
Can horses eat grapes?
Yes, horses can eat grapes in small amounts, and they are not known to be toxic to horses the way they are to dogs. Most horses enjoy them as an occasional treat. The catch is that grapes are high in sugar, so they should be limited, particularly for metabolic horses. Feed only a few at a time, choose seedless grapes, and treat them as a rare extra rather than a regular part of the diet.
Are grapes toxic to horses like they are to dogs?
Grapes and raisins are well known to be toxic to dogs, but there is no established evidence that grapes are toxic to horses, and horses are routinely fed small amounts without harm. That said, equine research on grapes is limited, so moderation is wise. The main practical concern for horses is the sugar content, not toxicity. When in doubt, keep portions small and ask your vet.
Are grapes safe for horses with Cushing's or EMS?
Grapes are high in sugar, so they are a poor choice for horses with PPID, EMS, or insulin dysregulation. The sugar can raise insulin and laminitis risk in these horses. A metabolic horse should not be fed grapes as a regular treat. If you want to reward an insulin-sensitive senior, choose a low-sugar commercial horse treat instead, and confirm the plan with your vet.
Can horses eat raisins?
Raisins are simply dried grapes, and like grapes they are not known to be toxic to horses, but they are very concentrated in sugar, which makes them a worse choice than fresh grapes for any horse and especially for metabolic ones. A few raisins now and then are unlikely to harm a healthy horse, but there is little reason to feed them. Low-sugar treats are a smarter pick.
How many grapes can I give my horse?
A small handful of grapes is plenty for an average healthy horse, and far fewer or none for a metabolic one. Grapes are a treat, not a feed, so keep them a tiny fraction of a forage-first diet. Because they are sugary and easy to overfeed, it is best to offer just a few at a time. Choose seedless grapes and avoid making them a daily habit.
Can grapes cause choke in horses?
Whole grapes are small, so choke is less of a concern than with apples or carrots, but a senior with very poor teeth that bolts a mouthful could still have trouble. To be safe, you can halve grapes for an older horse, and always feed only a few at a time so the horse is not gulping handfuls. As with any treat, watch a senior the first time it tries them.
