All dewormers were highly effective when they were first introduced, but over time parasites have developed resistance to many drugs. The product labels reflect results of studies performed when the dewormers were first developed—before the worms developed resistance—and drug companies have not been required by the FDA to modify labels to reflect current levels of effectiveness. It’s possible that the drug you choose to deworm your horses might not be doing what you expect. Are your horses at risk?

Considering horse populations are transported, mixed and often graze shared pastures, the transmission of resistant parasites is often unavoidable. In this free report, we provide the horse owner and caretaker with an overview of parasitic resistance to treatment and how you can overcome it.
