A. This depends on the age and condition of the horse as well as prior fecal results. Older horses generally have fewer issues due to a natural worm resistance that has developed over time. Young horses, especially those under three years of age, need more frequent testing. As a rule of thumb, many equine veterinarian suggest fecals be done at least four times a year for adult horses. If a horse is under three years of age, every other month is best. This schedule should be followed until there are few to no parasites seen on a few consecutive samples. Then the time between samples can be increased.
