How often should a horse be dewormed?

Having a horse involves many responsibilities and things you have to learn along the way that you may not have known after buying a horse for the first time. So if you want to buy a horse or you already have one, this is what we have learned with wormless horses that can help you get started right away.

So how often should a horse be weaned? Deworming the horse can be different for all horses, so first it may be best to ask your vet for suggestions. However, what we have done for many years is 2 to 4 times a year, usually every season or every other season. Starting with spring, summer, fall and winter. If yours the horse has been dewormed before that is enough.

Why should a horse be dewormed?

Horses may be at risk of developing gastrointestinal parasites that are also known as worms. Now there is so much more to say, just finishing the horse without a worm every so many weeks. You may not have to cuckoo the horse. If you only have 1-2 horses, you may want to contact your veterinarian.

If a horse is over 3 years old and grazes on its own most of the time, this is the main candidate for not having to be dewormed. Have a fecal test done by your veterinarian and you will have checked. Make sure the horse has not been dewormed in 12-16 weeks, so that they know that what is happening in the feces is natural. Many horses over 3 years old can fight worms on their own without the need for worms.

Just follow what works in your area. Places with a lot of humidity and warm air will cause more worm problems. If you have a harsh winter, for example, it is cold, for example, you probably do not need worms or when it is hot and dry.

How does a worm get a horse?

Horses usually receive worms from other horses that have had worms and grazed on the same pastures. Unfortunately, most of the time you can’t get infected. As your horse grazes eggs and worm larvae are simply ingested and infected. The infection in a pasture will last for a long time, there really is no way to completely clean an infected pasture.

4 main types of worms that affect horses

  • Blood and red worms
  • Round worms
  • You had
  • Bots

Tips and tricks to create an environment with fewer worms

  • Keep stables clean at least daily
  • Clean and change the water frequently
  • Sprinkle horse manure over unused pasture
  • If you spread manure on the horse’s pasture, try to go with cows and goats to clean up leftover larvae
  • Harvesting and hauling pastures where manure is spread will also reduce the risk. Maybe try mowing 2-3 times a year if you don’t graze there. You can drag with a mattress to a real dragger just to break the manure faster
  • Group horses by age so that younger horses do not come into contact with worms until they are 3 years old.
  • Pasture rotation is essential every 6-8 weeks if pastures are large enough
  • If possible, feed the horses while they are in stables on hay racks
  • New horses are kept separate until you know the general health of the horse

Symptoms of worms in horses (How do you know if your horse has worms?)

  • Colic
  • Diarrhea
  • Not eating / Loss of appetite
  • The coat becomes boring

How to deworm the horse?

Make sure you have passed all the checks such as asking your veterinarian, doing a fecal test and supplying your veterinarian with any medication the horse takes before administering deworming.

  • Be sure to dose the horse well. Most doses are for 1,200 pound horses. If your horse is bigger, you may need more if it is for a mini horse, you may need a little less. Most horses, even if 1,000 pounds can control the dose, is no problem.
  • We have always used pasta and find it easier. Your horse may not like the taste, so you can feed and water earlier to make sure they don’t go hungry.
  • Make sure all the hay and everything is wiped out of your mouth.
  • Insert the syringe into the horses’ tongues by lifting the lips towards the back of the mouth.
  • There is a gap between canines and incisors perfect for the syringe.
  • Once inserted, press the plunger down to squeeze the medication into your mouth. Be as fast as possible so as not to disturb them.
  • Once finished, be sure to keep it down so they don’t spit and swallow everything.

Worm horses on an empty stomach

You can deworm horses on an empty stomach. I wouldn’t do it the first time, but if they see if they take the worm and then eat it. They may not eat until they get that worm flavor out of their mouth.

How to deworm horses naturally

Pasture management is probably the best way to deworm horses. In cold climates, this is much easier, as long winters take care of most worm problems. If this is combined with regular fecal examinations, it should be sufficient for most areas.

Real natural dewormers, such as diatomaceous earth, have been shown not to work, so don’t waste your money.


Try to keep your pastures as clean as possible and horses away from your manure as much as possible. This will lead to fewer worm problems.

  • No worms if not needed.
  • Talk to your veterinarian for local details.
  • If possible, turn the pastures with other livestock.
  • cut pastures and drag them several times better during the year.

What is the best horse worm?

Depending on who you ask, they will have different opinions. First, ask your veterinarian. Most people rotate between ivermectin, something with praziquantel, moxidectin, and equimax. This should be enough for most areas and scenarios.

The reason you ride a bike is because what one worm won’t get to the other will usually cover so you have all the bases covered. In addition, horses and worms can become more immune to certain worms, which will also help prevent it.

The purpose of turning is to cover more than a horse will come in contact with. Thus, with rotation you get the best coverage against the four main parasites during their different life cycles.

Since most areas of the world have different climates, you will need to look a little further. With the accumulated resistance from worms, this was a common problem about 10-20 years ago.

It was not until Ivermectin came out that this problem seemed to solve itself. Scientists have claimed that so far this problem of worms becoming immune to treatments has been solved. The way to prevent this from happening is not excessive use of ivermectin and it still circulates worms.

There are currently 4 classes of chemical worms available that are considered anthelmintic. There are benzimazoles, ivermectins, moxidectin, and pirantels (such as strongid). So if you worm your horse 4 times a year, you can only do a four cycle every three months, which is the easiest way to do it.

However, this does not mean that all horses need to be dewormed 4 times a year. You may only need to deworm the horse twice a year, in which case you will have a two-year cycle with all four classes.
