Important Factors to Consider

Worms can destroy your horse’s internal organs and cause unwanted health. So, you will have to be thorough about choosing the right dewormer for your dog. Here are some important factors you will need to consider when choosing the right one.

Type of Worms

First, you will need to be sure which worm has infected your horse. The term “worms” is used to define a broad variety of parasites. Not matching the dewormer with the type of wormer for horses can result in an ineffective treatment. Dewormers only work on the type of worms that it is meant for. Remember that no dewormer can kill all kinds of worms and only treats a range of worm types.

Here are some of the most common types of worms in horses:

  • Pinworms

Eggs are usually picked up by horses from contaminated bedding, water, feed and may also be present on grooming materials, tail wraps, and even stalls and fence posts. It is not as dangerous as other types of worms and usually causes itching around the horse’s tail and rectum.

  • Tapeworms

Probably the most common and least worrisome type of all, tapeworms are contracted during grazing when your horse ingests mites found on plants and reside in the intestine, living off of the food which comes to them. Diarrhea and mild colic are the common symptoms of a horse infected with numerous tapeworms.

  • Bots

During the warm seasons, bot flies usually swarm around horses with the purpose of finding a place on the horse to lay eggs. After the eggs are laid, the horse may ingest them when it licks itself.  Once ingested, these parasites attach themselves to the intestines, mouth, tongue or lips and burrow into these tissues, causing poor overall conditions and mild colic.

  • Ascarids or Roundworms

Quite dangerous to foals and horses under the age of two, ascarid larvae migrate into the blood vessels and carried to the lungs and liver when ingested. These immature worms will eventually get swallowed and mature in the small intestine, completing their life cycle. Since the larvae migrate through the lungs, young horses may develop a respiratory disease, colic and poor weight gain.

  • Bloodworms (Small and Large Strongyles)

Ingested by horses when grazing in pastures, blood worm egg hatch and climbs grass blades where they are swallowed. Older and young horses are more susceptible to encrusted small strongyles with larvae burrowing in the intestines. A huge number of small bloodworms may cause diarrhea, colic, weight loss and an overall poor condition.

Meanwhile, large bloodworms can be very dangerous to organs and weaken a horse’s abdominal artery walls. The most common symptoms include colic, weight loss, and diarrhea.

  • Threadworms

Threadworms can be highly dangerous to foals and young horses. Foals may be infected by nursing from a mare infected with larvae. These parasites live in the intestinal tract and may cause weakness and diarrhea in young horses.

Age of the Horse

It is strongly suggested that all foals should be dewormed initially at 1 – 2 months of age. After that, treatment needs to be repeated every 30 – 60 days until the age of one. At this time, the one-year-old horse can be placed on the same deworming schedule as other horses.

The Form and Type of Medicine

Dewormers for horses come in various forms— liquid, pellets, and the most common of all, paste. You will have to decide which one would be convenient for your horse. The pellet and liquid form should give you the opportunity to mix it up with a regular diet for easy feeding. Meanwhile, paste is the most favorite since they come in the right dosage and easy to administer on horse’s mouth.

Next, you will have to consider what kind of medication you should get. As I have mentioned before, horses no wormer can kill all kinds of parasite. Here are some type of medication and the parasites they kill:

  • Moxidectin Paste and Praziquantel

Removed and control small and large strongyles, pinworms, ascarids, stomach worms, hairworms, and bots.

  • Ivermectin Paste and Praziquantel

Removes and control small and large strongyles, hairworms, pinworms, lungworms, stomach worms, bots, and ascarids.

  • Pyrantel Pamoate

Removes and control small and large strongyles, pinworms and roundworms.

  • Fenbendazole

Removes and controls small and large strongyles, pinworms and ascarids.

  • Pyrantel Tartrate (Daily Dewormers)

Provides continuous protection from small and large strongyles, pinworms and ascarids.

Horse’s Weight and Dosage

Avoid the weight-guessing game when it is time to deworm your horse. Most wormers for horses comes in packs of granules or powder for adding to food or syringes for oral administration. They are clearly marked with dosing instructions based on the weight of your horse and needs to be followed carefully in order to avoid underdosing or overdosing.

In addition, you will have to consider carefully some individual needs such as foals, miniature breeds or horses with underlying health conditions. Ask your vet for suggestion if you are not so sure about this.
