Why Does My Horse Have Diarrhea: The Core Reasons

Why Does My Horse Have Diarrhea? Diarrhea in horses is a sign that something is wrong and should be addressed as soon as possible. There are many different causes of diarrhea, including infection, parasites, dietary changes or allergies. Infections can come from bacteria, viruses or fungi which can cause inflammation of the digestive tract and lead to diarrhea.

Parasites such as tapeworms or roundworms can also cause intestinal issues leading to loose stools. Dietary changes such as sudden increases in carbohydrates or sugar can also result in diarrhea if not properly managed by slowly introducing new feed into their diet over time. Lastly, allergies to certain grains may be a contributing factor if your horse has been exposed to them recently.

If you suspect your horse has diarrhea it’s important to act quickly by contacting your veterinarian for further assessment and advice on treatment options which will depend on the underlying cause of the problem.

Diarrhea in horses is a common problem and can be caused by a variety of factors, including changes in diet or environment, parasites, bacterial infections, colic and more. It’s important to identify the cause of your horse’s diarrhea so you can take the appropriate steps to treat it swiftly. If left untreated, diarrhea can lead to serious health issues such as dehydration and weight loss.

Be sure to monitor your horse closely and seek professional advice if their symptoms persist or worsen.

What to Give a Horse With Diarrhea

When dealing with a horse that has diarrhea, it is important to keep the animal hydrated. Offer the horse plenty of fresh water and electrolytes throughout the day and provide hay or other suitable feed that is high in fiber. Additionally, probiotics can help to restore beneficial bacteria in your horse’s digestive system which may help relieve symptoms associated with diarrhea.

Certain medications are also available from your vet if needed.

What Do You Give a Horse With Diarrhea?

Diarrhea in horses can be a symptom of many underlying issues, so it is important to take your horse to the vet if they are showing signs of diarrhea. Once you have been given the all-clear from your vet and know that there is no serious underlying issue causing diarrhea, it is important to address how best to treat it. The key here is to provide plenty of fluids as dehydration can become an issue with chronic or severe cases of diarrhea.

You should also offer small amounts of plain bran or oat hay as this can help bind any loose stool. An electrolyte supplement may also help rehydrate and replenish minerals lost during loose stools, but always speak with your veterinarian before introducing something new into their diet. In some cases, medications such as antibiotics may be necessary for treating an infection that caused the diarrhea; again make sure you speak with your veterinarian first about what’s best for your horse’s specific condition.

Lastly, make sure you keep up good hygiene practices around your barn and paddocks by cleaning out stalls regularly and providing clean water sources daily – this will help prevent further spread of disease among other horses on the property!

Can Hay Give Horses Diarrhea?

Yes, hay can give horses diarrhea. Hay is the primary source of nutrition for horses and it is important to feed them hay that is free from mold or dust. If your horse eats contaminated hay, it can cause gastrointestinal upset leading to diarrhea.

Horses are also sensitive to changes in their diet; if you switch types of hay suddenly, this too could cause digestive issues resulting in diarrhea. Other potential causes of equine diarrhea include parasites, bacterial infections, colic and poor quality water sources among others. It’s important to consult a veterinarian if your horse has any signs of illness such as weight loss or loose stool so they can diagnose the underlying cause and provide treatment accordingly.

What Home Remedy Can I Give My Horse for Diarrhea?

If your horse is suffering from diarrhea, it’s important to take the proper steps in order to get them feeling better as soon as possible. Thankfully, there are several home remedies you can try before seeking out veterinary help. One of the most effective home remedies for horses with diarrhea is apple cider vinegar and electrolyte solutions.

Mixing one part apple cider vinegar with four parts water and giving it to your horse twice a day can help restore their digestive balance and reduce any acidity caused by the diarrhea. Additionally, providing an electrolyte solution such as Pedialyte or Gatorade mixed with water (one part solution/four parts water) will also help replenish lost electrolytes which are often depleted during bouts of diarrhea. You should feed this mixture two to three times a day until symptoms subside.

Another good remedy for horses is probiotics; these friendly bacteria aid in digestion and restoring gut bacteria balance naturally without harsh drugs or chemicals that could potentially further upset your horse’s stomach.

Can Worms Give Horses Diarrhea?

Horses are vulnerable to many different parasites, worms being one of the most common. While there are various types of worms that can cause digestive issues in horses, they can also be a source of diarrhea. In particular, large strongyles (also known as bloodworms), small strongyles, and pinworms have been linked to cases of diarrhea in horses.

Large strongyles tend to move through the horse’s intestine wall causing irritation which may result in inflammation and an increased chance for infection. Small strongyles can infect the intestinal walls leading to changes in absorption rate resulting in diarrhea. Pinworms live inside the colon where they lay eggs which causes inflammation and results in loose stools or even bloody feces due to irritation from their presence within the colon tissue itself.

How To: Treatment Options for Equine Diarrhea


In conclusion, it is important to recognize the signs of diarrhea in horses and take immediate action. If your horse has diarrhea, contact your vet for a proper diagnosis and treatment plan. It’s essential to provide plenty of water and electrolytes as well as keep an eye on the diet to ensure that the horse is getting all its nutritional needs met.

With proper care, you can help your horse recover from their bout of diarrhea and get back to feeling healthy again!
