The practice of feeding marshmallows to horses has sparked a lot of conversation and disagreement among horse owners and equestrian specialists. Humans love marshmallows as a delicacy, but many people are uncertain if they are suitable or safe for horses.

Some horse owners feed marshmallows to their horses as a special treat or as a way to reward good behaviour, while others believe that horses should only be fed foods that are specifically designed for their nutritional needs.

If you're considering feeding marshmallows to your horse, it's important to consult with your veterinarian or equine nutritionist first. They can help you determine whether marshmallows are safe and appropriate for your horse, and provide guidance on how to incorporate them into your horse's diet in a healthy way.

Can Horses Eat Marshmallows?

No, horses should not eat marshmallows. Marshmallows are typically made with sugar, corn syrup, gelatine and flavourings. The sugar in marshmallows can be difficult for horses to properly digest and can cause digestive problems. Consuming too much sugar can also lead to weight gain and other health issues. Therefore, it is generally not advisable to feed horses marshmallows.


What Are Marshmallows?

Marshmallows were originally made from the sap of the mallow plant, hence the name. However, modern marshmallows are made with sugar, corn syrup, gelatine, and flavourings. They are often dusted with a coating of corn starch or confectioners' sugar to prevent them from sticking together. Marshmallows can come in different sizes and shapes, including mini marshmallows, jumbo marshmallows, and animal-shaped marshmallows. Today, marshmallows are popular in recipes such as s'mores, rice crispy treats, and hot cocoa.

Feeding Marshmallows to Horses

Given that they are composed of non-toxic ingredients like sugar, corn syrup, gelatine, and flavourings, marshmallows are usually regarded as safe for horses to consume in tiny amounts. But it's critical to remember that marshmallows, which can be high in sugar and calories, are not a normal component of a horse's nutrition.

When eaten in large amounts, they can cause digestive problems for horses by upsetting the delicate balance of their digestive system. Consuming too much sugar can lead to weight gain and other health issues like laminitis, which is an inflammation of the hoof structures. Additionally, marshmallows do not provide many nutritional benefits to horses since they are mainly sugar.

Health Risks of Feeding Marshmallows to Horses

Digestive discomfort

Digestive discomfort is one of the main health risks associated with marshmallows and horses. The high sugar content can cause stomach problems and other digestive issues in horses. This can lead to vomiting, diarrhoea, and loss of appetite. Furthermore, it can also increase the risk of colic. Therefore, it is best to avoid feeding marshmallows to horses.

Weight Gain

Weight gain is another potential health risk associated with marshmallows and horses. The high sugar content can lead to weight gain in horses, as sugar is a source of empty calories. In addition, excess sugar can lead to an imbalance in the horse's diet, preventing them from getting the essential nutrients they need. Therefore, it is best to avoid feeding marshmallows to horses to prevent weight gain.

Tooth decay

Consuming too much sugar can cause tooth decay in horses. High sugar content in marshmallows can lead to an overgrowth of bacteria in the horse's mouth which can weaken the enamel and cause cavities.


The sugar in marshmallows can cause a rapid spike in blood sugar which can lead to an increase in energy levels, leading to hyperactivity in horses. This can have dangerous implications for both the horse and rider as it can lead to unpredictable behaviour such as running, bucking, rearing, bolting, etc. Hyperactivity can also lead to exhaustion, dehydration, and heat exhaustion.

Nutritional deficiencies

Nutritional deficiencies in horses can be caused by consuming too much sugar, including from marshmallows. Too much sugar can lead to a lack of essential nutrients, such as vitamins and minerals, as well as important digestive enzymes. This can lead to weight loss, muscle wasting, poor coat quality, and weakened immunity.


Alternatives to Marshmallows That Horses Can Safely Consume

There are many alternatives to marshmallows that horses can safely consume, such as grass, hay, oats, apples, carrots, and other healthy snacks. These alternatives will provide essential vitamins and minerals while still providing a sweet treat for your horse. Additionally, there are also many special treats made especially for horses which are designed to provide balanced nutrition while being tasty and enjoyable.

Here are some other alternatives to marshmallows for horses: 

  • Grain mixes and cubes 
  • Vegetables like carrots, celery, and cucumbers 
  • Fruit such as apples, strawberries, and blueberries 
  • Herbs and spices like ginger, cinnamon, and mint 
  • Commercial horse treats made with natural ingredients 
  • Homemade treats made with healthy ingredients like oats and honey 
  • Hay cubes or pellets

How to Recognize if Your Horse Has Consumed Too Much Sugar

Signs that your horse has consumed too much sugar include weight gain, dull coat, digestive upset, and lethargy. If you suspect your horse has eaten too much sugar, look for signs of over-consumption such as excessive food consumption or an increase in drinking water. Monitor your horse's behaviour for any changes and seek veterinary advice if necessary.

Here are a few other tips for recognizing if your horse has consumed too much sugar: 

  • Check for changes in eating habits. If your horse is eating more than usual or grazing more often, it could be a sign he's consuming too much sugar. 
  • Look for a decrease in physical activity. Excessive sugar consumption can lead to lethargy and a decreased appetite for exercise. 
  • Monitor your horse's weight. Weight gain can be an indicator of sugar consumption. 
  • Observe the texture and shine of your horse's coat. Dullness of coat or patchiness can be an indication of excessive sugar consumption.

Concluding Words

Marshmallows contain a lot of sugar which can be difficult for horses to digest. This can lead to potential health risks such as digestive discomfort, weight gain, tooth decay, and hyperactivity. Additionally, sweet snacks like marshmallows shouldn't be given to horses who have metabolic disorders like insulin resistance or equine metabolic syndrome because they can make them worse. Horse owners should look for alternatives to marshmallows that horses can safely consume, monitor their horse's behaviour for any changes, and seek veterinary advice if necessary.
