How often should you worm horses?

Most horses only need to be dewormed once or twice a year. Before deworming in the spring, we recommend having a fecal egg count (FEC) done. This procedure allows us to measure the number of worm eggs a horse is shedding in its feces. Based on the results, we will recommend whether you need to deworm your horse.
