How to Check a Horse for Worms: A Comprehensive Guide
Checking a horse for worms is essential for maintaining its health and well-being. Regular deworming and monitoring can prevent serious health issues. This guide will walk you through the steps to identify if your horse has a worm infestation and how to manage it effectively.
What Are the Signs of Worms in Horses?
Horses with worm infestations may exhibit a variety of symptoms. Recognizing these signs early can help you take prompt action.
- Weight loss despite a good appetite
- Dull coat and poor hair quality
- Potbelly appearance, especially in foals
- Colic symptoms, such as abdominal pain
- Diarrhea or loose stools
- Lethargy and lack of energy
How to Perform a Fecal Egg Count Test?
A fecal egg count test (FEC) is a reliable method to determine the presence of worms in your horse. This test measures the number of worm eggs per gram of feces, helping you assess the worm burden.
- Collect a Sample: Use a clean glove or container to collect a fresh fecal sample from your horse.
- Store Properly: Place the sample in a sealed bag or container and keep it cool until testing.
- Send to a Lab: Submit the sample to a veterinary laboratory for analysis.
- Interpret Results: Consult with your veterinarian to understand the results and plan a deworming schedule.
What Are the Common Types of Horse Worms?
Understanding the types of worms that commonly affect horses can help in selecting the right treatment.
- Large Strongyles: Once common, now less so due to effective deworming.
- Small Strongyles: The most prevalent, causing weight loss and colic.
- Roundworms (Ascarids): Common in young horses, leading to respiratory issues.
- Tapeworms: Can cause colic and intestinal blockages.
- Pinworms: Cause tail rubbing and skin irritation.
How Often Should You Deworm Your Horse?
The frequency of deworming depends on several factors, including age, environment, and the results of fecal egg counts.
- Foals: Every 6-8 weeks until they are one year old.
- Adult Horses: Typically 2-4 times a year, based on FEC results.
- High-Risk Horses: More frequent deworming may be necessary for horses in high-risk environments or with high FEC results.
What Deworming Products Should You Use?
Choosing the right dewormer is crucial for effective treatment. Here’s a comparison of common deworming products:
| Dewormer | Active Ingredient | Target Worms | Frequency |
|---|---|---|---|
| Ivermectin | Ivermectin | Large and small strongyles, bots | Every 6-8 weeks |
| Fenbendazole | Fenbendazole | Ascarids, pinworms | Once or twice a year |
| Pyrantel Pamoate | Pyrantel | Tapeworms, strongyles | Every 6-8 weeks |
| Praziquantel | Praziquantel | Tapeworms | Twice a year |
How to Develop a Deworming Schedule?
Creating a deworming schedule tailored to your horse’s needs ensures optimal health.
- Consult a Veterinarian: Work with your vet to determine the best schedule based on FEC results.
- Rotate Dewormers: Use different classes of dewormers to prevent resistance.
- Monitor and Adjust: Regularly assess your horse’s health and adjust the schedule as needed.

What Are the Risks of Over-Deworming?
Over-deworming can lead to drug resistance, making treatments less effective. It’s important to use dewormers judiciously and base treatments on fecal egg count results.
Can Worms Affect a Horse’s Performance?
Yes, worms can significantly impact a horse’s performance by causing weight loss, colic, and lethargy. Maintaining a regular deworming schedule helps keep your horse in peak condition.
How Do You Know If a Dewormer Is Working?
After administering a dewormer, conduct a follow-up fecal egg count test in 10-14 days to check for a reduction in egg counts, indicating the dewormer’s effectiveness.
Should You Deworm All Horses in a Herd Simultaneously?
Yes, deworming all horses in a herd simultaneously helps reduce the risk of re-infestation and ensures consistent parasite control.
