The Old Way: Deworming may be something you’ve been doing the same way for as long as you can remember—most likely rotating between ivermectin, pyrantel, and a handful of other chemicals about every eight weeks or so.

However, as parasite resistance and the lack of new dewormers in the pipeline become increasing concerns, more and more horse owners, barn managers, and veterinarians are rethinking the way they deworm horses.

The Smarter Way:
Your horse is an individual, and we now know he should be dewormed that way.

The first step is to ask your vet to perform a “fecal egg per gram” test, also known as a “fecal egg count.” This test should be done at least once per year, or as often as your vet recommends. Based on whether horse is a low, medium, or high shedder, your vet can help you choose which chemical dewormer to use and how often. Targeting your horse’s specific deworming requirements is the key takeaway, and those factors will vary quite a bit based on how heavy an egg shedder he tends to be, your geographic location, how often your horse is exposed to other horses, and the manure management on your farm.
