Sugar cubes usually only contain sugar. That means that they do not have any nutrients or minerals that are healthy for horses.

Sugar cubes can cause weight gain as well as gastrointestinal issues if fed too often. Overall, sugar cubes are not considered a healthy horse treat and many horse owners prefer to give their horses healthier treats. (source)

How Many Sugar Cubes Can a Horse Have Daily?

Three to four sugar cubes is all that any horse should consume daily. That small amount, combined with a horse’s large weight, causes only a small spike in glucose levels.

Horse treats like sugar cubes are often used to help when training horses, but they should still be limited to only 3 to 4 each day. Here are a few ways you can use just a few sugar cubes each day to help train your horse.

Putting Bridles On

Some head shy horses resist having bridles put on their heads. You can use a sugar cube as a reward when the horse lets you put their bridle on. Over time, the horse may see the bridle as a positive thing instead of something scary.

Ear Shy Horses

May horses dislike having their ears messed with. Whether you are putting a halter on them or clipping the hair in their ears, you can use a sugar cube as a treat when you are finished.  

Positive Reinforcement Training Treats

You can use a couple sugar cubes each day to provide positive reinforcement to a horse for performing other wanted behaviors. Simple things, like coming to you when they are called for, or listening to commands can be rewarded with treats.
