Horses that have difficulty chewing should have their cucumbers prepared in a way that is easy for them to eat and digest.


Cucurbitacin is a compound found in cucumbers that can cause gas buildup in horses, making them uncomfortable or even possibly leading to colic. Horses are unable to burp or belch, so if they experience any sort of pain after eating cucumbers, it is best to discontinue this treat. It is important to note that other healthy vegetables can be substituted for cucumbers.

Hyperkalemic Periodic Paralysis (HYPP)

The illness necessitates diligent diet management on the part of the horse owner. Paralysis occurs when the horse consumes anything high in potassium, so horse owners with HYPP-afflicted horses should avoid feeding them carrots and other high-potassium meals.


Feeding horses too many cucumbers can lead to overfeeding, so it is recommended to limit the number of cucumbers fed to one or two per week.
