Can Horses Eat Cucumbers?

Maintaining a balanced diet for your horse can make a world of difference for their overall health, looks, and performance but can horses eat cucumbers? That’s exactly what we’ll discuss in this article, so stick around.

And while many horses can eat anything you throw at them, some can be particularly picky about what gets into their mouths. However, preferences shouldn’t be your only concern here. Just because your horse can eat something doesn’t mean that it should. 

Can Horses Eat Cucumbers? 

Yes! Your horse can enjoy a quick snack of cucumbers. It’s one of the healthiest snacks for your horse as it’s low in sugar and calories. Not to mention, it’s rich in vitamins and minerals.

However, just like any other type of food, there are specific considerations and precautions that you need to keep in mind before feeding your horse cucumbers. 

Risks and Potential Side Effects

Benefits of Cucumbers for Horses

There are countless nutrition benefits of feeding your horse cucumbers, which are:

Cucumbers Are High in Water 

Drinking water alone isn’t sufficient for your horse to stay hydrated. They still need a considerable quantity of hydrated foods, especially on hot summer days. 

They Have Limited Carbs and Sugar Content

Cucumbers have little to no carbs or sugar content. They’re also low in calories, meaning that it won’t be a reason for the weight gain of your horse.

They’re Rich in Antioxidants

Antioxidants remove any free radicals inside your horse’s body; thus, they’re great for combating inflammation in horses. Cucumbers are a rich source of antioxidants. 

Cucumbers Are Full of Nutrients

Cucumbers are packed with vitamins D, K, C, and A, calcium, and potassium, which are important for your horse’s bone health and strength. 

Risks and Potential Side Effects

Despite their health benefits, cucumbers may cause some side effects in horses. The most common side effect is bloating and other gastrointestinal issues. 

This is because cucumbers contain a substance called cucurbitacin, which causes the build-up of gas in horses and even humans. However, since horses can’t belch or burp, it may irritate them much more than humans. 

It’s also worth noting that some horses are particularly sensitive to potassium, which cucumbers have plenty of. This is a condition called Hyperkalemic Periodic Paralysis (HYPP).

Cucumbers may also cause abdominal pain (colic). Colic is a particularly tricky condition to treat. Some horses may respond positively to medication, while others may require surgery or even euthanasia.


Before feeding your horse any cucumbers, keep these precautions in mind:

Keep the Portions in Check

Cucumbers are healthy, but they may do more harm than good if you don’t watch your horse’s consumption. Letting your horse eat too many cucumbers will make bloating more likely to happen and in a more severe way. 

The exact quantities depend on your horse’s health, genetics, and age. 

Wash the Cucumbers Carefully

Just like other commercially produced vegetables, the skin of cucumbers may collect chemicals and pesticides, which can be harmful to your horse. 

So, before feeding cucumbers to your horse, wash them thoroughly with clean water and maybe even peel the skin just to be on the safe side.

You might also consider feeding your horse organic cucumbers as these are free of chemicals.

Introduce the Cucumbers Gradually

If this is the first time your horse will be eating cucumbers, make sure that you introduce them gradually into its diet to see if your horse is sensitive to them. 

Risks and Potential Side Effects

Here are some of the symptoms that could show up on your pet horse if it’s susceptible to cucumbers:

  • Rolling
  • Infrequent pooping
  • Pawing on the floor
  • Loud gut noises
  • Low appetite
  • Hypersweating
  • Urination problems
  • Lethargy

If you notice any of these signs, stop feeding your horse cucumbers and take it to the vet as quickly as possible. 

You can start small and increase the quantities a bit over time once your horse starts getting used to it.

However, remember that you still need to keep the quantities small to prevent gastrointestinal problems.

Make Sure That Your Horse Actually Likes Cucumbers

Not all horses enjoy cucumbers. So, if your pet horse doesn’t look like it really enjoys eating cucumbers, replace it with a different snack.

What Vegetables Can Horses Eat?

Horses can eat corn, lettuce, carrots, sweet potatoes, squash, turnips, and celery. All of these veggies are packed with vitamins and minerals, and your horse will enjoy them in small quantities. 

What Foods Are Harmful to Horses?

Here’s a list of foods that your horse shouldn’t consume to avoid any harm:

  • Cabbage
  • Avocado
  • Meat products
  • Persimmons
  • Rhubarb
  • Fruits with stones
  • Cauliflower
  • Tomatoes
  • Broccoli
  • Potatoes
  • Rhubarb
  • Bran products

However, your horse can consume fruits with stones after you remove the stones from them. If they’re ingested without the removal of stones, they could choke your pet horse. 

How to Feed Your Horse Cucumbers

Horses have large mouths and teeth, meaning that they can probably eat cucumbers of any size. However, keep in mind that you need to consider the health of your horse’s teeth. For example, some horses may struggle to chew and swallow cucumbers if they’re whole or cut into large pieces. 

So, one horse-friendly way to serve a cucumber is to slice it into round small or medium-sized pieces and feed them one by one.

How to Feed Your Horse Cucumbers

You also need to ensure that your horse eats the cucumber slowly to avoid choking. Some people serve cucumbers to horses shredded or blended, but that’s only recommended if your horse can’t chew small pieces of cucumbers for whatever reason. 

Another option is to just sprinkle shredded cucumbers over your horse’s hay. 

How to Maintain a Balanced Diet for Your Horse

Similar to any other pet, horses require some special care when it comes to dietary habits and needs. Here are some of the things that you need to consider:

Don’t Overfeed Your Horse With Grain

Too much grain may cause health issues for your horse down the line. For example, colic, one of the most common (and dangerous) digestive diseases, is primarily caused by excessive grain consumption. 

So, try to keep your horse’s grain intake to less than 11 pounds per day.

Introduce New Foods Gradually

Horses don’t like it when their diet changes frequently and aggressively. Introduce one new food at a time and do it gradually to give your horse adequate time to get used to it.

Feed Your Horse More Forage

Forage should make up more than half of your horse’s daily calorie consumption. It’s full of nutrients, such as protein and vitamins, making it the most important part of your horse’s diet. 

Ensure That Your Horse Can Drink Water Easily

Horses must stay hydrated round the clock to enhance bowel movement, improve digestion, and preserve skin and hair health. Always keep a bowl of clean water next to your horse.

Don’t Underfeed Your Horse

Horses require a daily amount of calories to maintain a healthy weight. On average, horses at rest require 15,000 calories/day, while horses that do some light work may require up to 25,000 calories/day. 

However, if your horse engages in heavy physical activities, around 33,000 calories/day would be ideal.

Supplement Your Horse’s Diet With Vitamins

Vitamins like vitamin C, D, B6, and E are essential for your horse’s health, so make sure that its diet is filled with vitamin-rich foods. 

You might also want to consider adding vitamin supplements to your horse’s diet, but it’d be best to consult a vet before doing this. 

Monitor Your Horse’s Stress Levels 

A horse may go through periods of stress, which can affect its eating habits. If you notice that your horse isn’t feeding normally, consult a vet and see what diet changes would suit your horse’s condition.

Ensure That Your Horse’s Diet Contains Enough Minerals

Horses need minerals to keep their body functions operating in their best condition. Without minerals, your horse’s skin, hair, immunity system, and vision will suffer.

Final Words

So, can horses eat cucumbers? Yes! Giving your horse a few cucumbers will provide it with essential vitamins and minerals. And since they’re low in calories, cucumbers can be a great way to reduce your horse’s risk of obesity and high blood sugar levels.

Just make sure that you limit the portions and wash the cucumbers thoroughly before introducing them to your horse.

Of course, if your horse shows any signs of irritation after eating cucumbers, don’t feed them cucumbers again. 

And remember, adding variety to your horse’s diet is essential for its health and wellbeing. So, don’t rely on cucumbers heavily and leave room for other healthy veggies and foods.
