Horse Dewormers

Tell parasites to hit the trail and help keep your main mare healthy and feeling her best with horse dewormers. It's common for horses to get worms because the parasites are consumed as eggs or larvae in grazing pastures. When your horse has an uncontrolled infestation, she may experience health issues like poor body condition, tummy issues, colic and more. That's why it's important you use dewormers for horses to help manage worms.

Horse dewormers are administered orally. You'll find some come in a gel form that are administered using a syringe. Many feature an enticing flavor to encourage her to take it all and make a more pleasant experience for both of you. There are also some horse wormer supplements that look just like pellet feed and can be added to your gal's usual meal.

Unlike many other medications, you should switch up your horse wormers and not use the same one each time. That's because parasites can develop immunity to the medicine, making it less effective. So, the best dewormer for horses for your horse will change. Work with your vet to come up with a good schedule and medicine rotation. She might suggest a fecal egg count so that you can come up with the best plan of action.

There are many ways you can help keep your equine friend healthy and ready to saddle up and Chewy is here for all the horse health and wellness products you could ever need. We offer horse pest control to address other pest woes for your horse, like flies. And we also have horse vitamins and supplements to help her feel and look her best. If your vet has a special plan in mind, you can easily get prescription medication for horses online. Of course, you'll find other horse supplies to satisfy her needs. Happy trails to you and your hoofed friend when you shop Chewy.com for the best dewormers for horses!

Frequently Asked Questions about Horse Dewormers

How often do you deworm a horse?

You should deworm a horse as often as your roundworm egg count deems it necessary. Check worm egg counts regularly, especially during the grazing season, and treat horses with high worm egg counts and those who are more susceptible to problems, like yearlings and older friends. Tapeworms are handled differently, and many horses should be treated twice a year. Deworming frequency varies from one horse to another, so you should always check with your veterinarian to come up with the best deworming schedule for your neighing neighbor.

What is the best dewormer for horses?

The best dewormer for horses varies because parasites can develop immunity to the medicine, potentially making it less effective. As a best practice, you should change and rotate the dewormer often with guidance from your vet.

Can you over-deworm a horse?

Yes, you can over-deworm a horse if you treat for worms unnecessarily. Previous best practices suggested deworming on a regular schedule. However, needs vary between horses and not every horse needs to be dewormed as frequently. Current thinking is that fecal egg count tests should be used to determine if treatment is needed. While treating more often than necessary is unlikely to cause your horse to become ill, it may cause parasite resistance to dewormers. It is best to work closely with your vet to determine the right schedule for your gal.
