Before we move on to talk about various aspects of feeding chocolate to horses, let us first make sure whether horses like to eat chocolate or not?

First and foremost, horses are not known to be fussy about what you feed them. Moreover, they have a poor sense of what is or isn’t good for their health. Therefore, if you feed your horse chocolate, they are most likely to eat them.

However, some horses do have more reservations about their food than others. Though less likely, it is possible that your horse might not like the taste of chocolate.


Why is chocolate harmful to horses?

Why is chocolate harmful to horses

In the first section of the article, we stated that chocolate is harmful to your pet’s health. In this section, we will tell you why.

To determine why something is healthy or harmful for an animal, it is essential to understand what it is made up of. On that note, let us take a look at the basic contents of chocolate and how they affect your horse.



All of us know that chocolate comes from the cacao plant. Theobromine is a bitter-tasting alkaloid present in the cacao plant. For humans, this alkaloid is not just harmless but also healthy, for it has a therapeutic effect on their blood sugar levels.

However, for horses, theobromine can prove to be lethal. The reason behind it is that the digestive system of horses, unlike humans, is not designed to digest/metabolize theobromine.

Therefore, any amount of theobromine that enters their body remains inside and keeps building up until it reaches a highly toxic level. It can then lead to health problems such as internal bleeding, seizure, or heart attack. In many cases, too much theobromine in a horse’s system has ended up taking their lives.



Caffeine is another major ingredient of chocolate. The job of caffeine is to increase the blood pressure and heart rate of its consumer. Humans use this stimulant to keep them energized and productive throughout the day.

However, caffeine can have adverse effects on your pet. Horses already have a faster heart rate than humans; using any supplement to enhance it can lead to hyperactivity and undesired behavior in them. Too much caffeine can also make them suffer from diarrhea and gastric bleeding.



Although the cacao plant doesn’t naturally contain sugar, the processed chocolates that reach us contain varying degrees of sugar. A high quantity of sugar can create an imbalance in your pet’s blood sugar level and which can lead to metabolic syndrome and other health problems, obesity being one of them.


High-calorie content

Horses consume a sufficient amount of calories in their daily diet, and feeding them any calorie-rich treats such as chocolate can add too many calories to their body. It can make them overweight, which is the cause of a number of severe diseases such as Laminitis.


Is it okay to feed horses chocolate moderately?
