As time goes by, your gelding or stallion will collect dead skin cells, sweat, and dirt in his sheath. This can cause irritation and infection as it gets progressively worse. This debris will also collect at the urethral process (the opening at the tip of their penis). If it gets large and compact enough it is called a “bean” and can cause irritation and pain when your horse urinates. During the cleaning, the veterinarian will also be looking for wounds, tumors, and other abnormalities of the sheath and penis. Your male horse can be sedated and cleaned while standing. It is recommended to have this done once a year – typically when your horse’s teeth are checked.
