Common Causes of Horse Diarrhea and How to Treat It

Horses are majestic creatures that require a lot of care and attention. Unfortunately, they can sometimes become ill with various ailments, including diarrhea. Several factors can cause diarrhea in horses, and it is important to identify the cause to provide effective treatment. This article will discuss the common causes of horse diarrhea and how to treat it. 

What Causes Horse Diarrhea? 

An underlying condition or illness, such as an infection, colic, parasites, or a dietary issue, usually causes horse diarrhea. Some other common causes include:

Infections: Bacterial afflictions are the most ubiquitous basis of equine looseness of the bowels. These contagions can be acquired from polluted victuals or liquid or from liaisons with other horses that possess the disease. Viral infections can also cause diarrhea in horses, especially if they are not vaccinated against certain viruses. 

Parasites: Parasites such as roundworms, tapeworms, and bots can also cause horse diarrhea. These parasites live in the digestive tract and feed on your horse’s food. They can cause irritation and inflammation in the intestinal lining, leading to diarrhea. 

Dietary Issues: Horses with an unbalanced diet or fed too much grain may also develop diarrhea. Excess grain ingestion can overburden a horse’s digestion, resulting in gut aggravation and soreness, culminating in looseness of the bowels.

Colic: Colic is another common cause of horse diarrhea. Colic is a general term for abdominal pain or discomfort in horses due to gastrointestinal issues such as gas buildup or blockages in the intestines. Colic can lead to severe pain and discomfort for your horse, resulting in diarrhea if not treated quickly. 

Treating Horse Diarrhea 

Once you have divined the root of your horse’s diarrhea, you should commence treatment to impede additional harm to their well-being. Depending on what is engendering your horse’s diarrhea, there are multiple disparate remedies accessible:

Medication: If your horse has a bacterial infection causing their diarrhea, they may need pharmaceuticals or other medicaments to clear the contamination. If parasites are the cause, your vet may prescribe a vermifuge to eradicate the parasites. If your horse has colic, it may need body fluids and analgesic medications to facilitate relief of its indications.

Dietary Changes: If your horse’s diarrhea is due to an unbalanced diet or too much grain, you should immediately change their diet. Feeding them hay or other forage-based diets will help to keep their digestive system balanced and reduce the risk of diarrhea. 

Fluids: If your horse has severe diarrhea, it may become dehydrated, which can be dangerous. It is important to provide them with plenty of fluids to prevent dehydration. You can give them electrolytes or oral rehydration solutions to help replenish lost electrolytes and fluids. 

Preventing Horse Diarrhea 

The optimal approach to dealing with equine diarrhea is to forestall it from happening in the first place. Here are some ideas for avoiding horse diarrhea: 

• Make sure your horse is vaccinated against viruses or other illnesses that can cause diarrhea. 

• Feed your horse a balanced diet and limit grain to prevent overload of their digestive system. 

• Make sure your horse has access to clean water and food to prevent bacterial infections. 

• Regularly deworm your horse to remove any parasites that could cause diarrhea. 

• Monitor your horse’s health regularly for signs of illness or discomfort. 


Various components, including contagions, parasites, dietary deficiencies, and colic, can induce equine diarrhea. Therefore, it is essential to discern the source of your horse’s diarrhea so that you can apply the correct remedy. Medicines, dietary modifications, and liquids may be required to address the condition and avert desiccation. Additionally, consistent surveillance of your horse’s health and furnishing them with a well-rounded diet can help preclude diarrhea from the outset.
