Is Letting My Horse Stay Out in the Rain a Good Idea?

Rain is common, and horse owners often wonder whether Is Letting My Horse Stay Out in the Rain a Good Idea? After all, we humans generally prefer to stay warm and dry during wet weather, so it’s only natural for us to wonder if our horses have the same preference. In this blog post, we’ll dive into the topic and discuss the factors to consider when deciding if letting your horse stay out in the rain is a good idea.

Understanding Your Horse’s Natural Adaptations

 It’s important to remember that horses are highly adaptable and have evolved to survive in all kinds of weather conditions over millions of years. Their coats are designed to provide insulation and repel water, allowing them to remain relatively dry and warm even during a downpour. When horses are healthy and well-fed, their natural ability to withstand the elements should not be underestimated. Some horses even enjoy a good rainstorm.

Factors to Consider

  1. Temperature: One of the main things to consider is temperature. If it’s warm outside and the rain is relatively light, your horse should stay outdoors without any real concern. However, if the temperature drops or if the rain becomes cold, your horse could risk hypothermia, especially if they’re not provided with adequate shelter or a waterproof blanket. 
  2. Shelter availability: Providing someplace where your horse can find refuge from the rain if he wants to get out of the elements. Wind-driven rain is also a consideration when planning a structure. Can be as simple as a three-sided shelter or a run-in shed that allows your horse to get out of the rain when they choose. Providing shelter protects them from the elements and gives them a sense of security. Also, if the floor is raised, it can provide a dry place to stand or lie down. Lightning protection should also be a consideration when building a shelter.
  3. Coat condition: A horse’s coat is its first line of defense against wet weather. Regular grooming is needed to ensure that your horse’s coat remains healthy and capable of repelling water. Grooming also allows you to inspect its coat for any sign of a skin problem. If your horse’s coat is matted, dirty, or otherwise compromised, it may be less able to withstand wet weather. Unseasonably cold weather in the fall can cause problems because your horse may still need to grow in his winter coat, so care should be taken to ensure they are blanketed if they will remain outside. 
  4. Health and age: Young, healthy horses are generally more resilient to the elements than older, more senior horses or those with health issues. If your horse has a compromised immune system or other health concerns, it’s best to consult your veterinarian about whether or not your horse should stay out in the rain. A minor cold can turn into something serious if it is overlooked.
  5. Duration of rain exposure: Occasional exposure to rainy weather is unlikely to cause significant problems for most horses. However, prolonged exposure to heavy rain, especially in combination with cold temperatures, can lead to an increased risk of health issues, such as respiratory infections or skin conditions.
  6. Lightning: Is there lightning predicted? How serious is the weather?

Rain-Related Equine Health Concerns: Rain Rot, Rain Scald, and Thrush

While horses are naturally adapted to handle various weather, exposure to wet environments health issues can sometimes occur. This section will discuss three common rain-related health concerns: rain rot, rain scald, and thrush.

Rain Rot (Dermatophilosis)

Rain rot, also known as dermatophilosis, is a bacterial infection caused by the Dermatophilus Congolensis bacteria. This condition occurs when the bacteria take advantage of a compromised skin barrier due to prolonged wetness, causing painful scabs and hair loss. To prevent rain rot, ensure that your horse has access to a dry shelter and regularly groom to maintain a healthy coat. If you notice any signs of rain rot, such as crusty, scabby lesions, or hair loss, consult your veterinarian for treatment options, which may include medicated shampoos, antibiotic therapy, Fungus fighter, or Heal cream.

Rain Scald

Rain scald, also known as mud fever or pastern dermatitis, is another bacterial infection that affects horses in wet environments. This condition typically affects the lower limbs and is characterized by inflammation, hair loss, and scabs. It’s caused by the same bacteria responsible for rain rot and thrives in muddy or wet conditions. To prevent rain scald, keep your horse’s legs clean and dry, provide well-draining turnout areas, and avoid excessive hosing of your horse’s legs. As with rain rot, consult your veterinarian if you suspect rain scald, as they can recommend appropriate treatment options such as Fungus Fighter.


Thrush is a common hoof condition caused by a fungal infection (Candida spp.) that affects the frog area of the hoof. Thrush thrives in wet, dirty environments, leading to a foul-smelling, black discharge and a soft, spongy frog. Prolonged exposure to wet conditions, poor hoof hygiene, and inadequate hoof care can increase the risk of thrush. To prevent this condition, regularly clean and inspect your horse’s hooves, provide a clean and dry living environment, and schedule routine farrier visits. If you notice signs of thrush, consult your farrier or veterinarian for guidance on appropriate treatment, which may include cutting the affected area out or hoof care products such as Thrush Thrash.

Ultimately, whether or not to let your horse stay out in the rain is a decision that should be based on various factors, including the specific conditions at hand and your horse’s individual needs. Providing adequate shelter, monitoring your horse’s health, and ensuring they have a well-maintained coat are all essential steps in keeping your equine friend comfortable and healthy during wet weather.

While horses are generally well-equipped to handle wet weather, prolonged exposure to rain and wet environments can increase the risk of health issues such as rain rot, rain scald, and thrush. By taking proactive measures to maintain your horse’s coat and hoof health, providing access to shelter, and monitoring your horse for signs of these conditions, you can help protect your equine friend from the adverse effects of rain and wet conditions.

Remember that your horse’s welfare is of the utmost importance. If you are ever unsure about the best course of action, consult a veterinarian, farrier, or an experienced horse professional for advice. By taking these considerations into account and being proactive about your horse’s care, you can ensure that they remain healthy and comfortable even in the face of unpredictable weather.
