Some owners have "The Frenzy" down to a science, but others might forget to clean of one of the darkest—and possibly dirtiest—places in the barn: your gelding's or stallion's sheath.

The stigma that seems to be attached to sheath cleaning ranks up there with squeezing anal glands in dogs. Geldings (neutered male horses) and stallions produce a waxy discharge in their sheath area.

Sheath cleaning is more than just removing the smegma (waxy buildup that male horses excrete) from the sheath area. Although this wax is normal, it can become a problem if it builds up too much.
