Deworming Dos & Don'ts

The biggest mistake made deworming a horse is using only ivermectin wormers. If you only use one type of chemical class your horse can become tolerant, and your worming schedule will be ineffective. Below is a great chart used to describe the different Drug classes for wormers and why they are used.

In some cases, your Vet will come up with a rotational worming schedule directed especially for your born, as they will know the risks for parasites in your area.

Some prevention to parasites can be made by cleaning manure out of pasture frequently, as well as feeding your horses from a feeder rather than the ground.

Here are some factors that can result in a higher risk of parasites for your horse:

Horses being pastured in a dry lot (dirt lot)

Sharing pastures with cattle, goats or sheep

Hight Pasture Population ( Having one or more horses per acre of land)
