When to worm

It is ideal to use the minimum number of treatments possible in a year, as over-worming can lead to resistance.  Traditionally it has been recommended that you worm your horse every two months, but recently there has been some debate on whether that causes resistance build-up.  Today most veterinarians suggest worming at least twice yearly unless your horse is showing signs and symptoms of having worms.

In other words, you will need to deworm your horse after the first frost or cold front of the year and again in the spring. Here in Florida be aware of your horse’s condition during the hot summer months. Morevoer, keeping track of their fecal egg count will help to manage parasites and will give you a more accurate idea of when your horse needs to be wormed.  In addition, make sure one of the wormers that you select fights against tapeworms.


How to worm

Worming your horse should be an easy worry-free process. It really is all about the approach. If you act casually, stay calm, present it in a non-threatening way then things will go smoothly.  Most of today’s wormers have a flavor to make it more enjoyable for your horse.  Besides, you can always add a flavor to the outside of the tube such as honey or molasses so that your horse will come to look forward to the taste.

Have your horse safely tied, head down, and present the tube as you would a bit. Place the tube in the back of the mouth in the corner and depress the plunger slowly to ensure all of the product gets taken.

That simple.
