When it comes to caring for horses, one question often arises: should horses wear rugs in summer? While rugs are an essential part of horse care during colder months, their role during the warmer seasons is a topic that generates a fair bit of debate. After all, horses have evolved to deal with a wide range of temperatures and weather conditions. However, the introduction of summer horse rugs has changed the way many owners manage their horses' comfort during the hotter months.
Some believe that summer rugs are a must-have, providing crucial protection from the elements, while others argue that horses are perfectly capable of managing without them. So, what’s the truth? Let’s dive into the benefits, considerations, and potential drawbacks of using horse rugs in the summer.
It’s easy to assume that a horse rug in the summer might be unnecessary, especially considering that horses naturally grow a thinner coat during the warmer months. However, many horse owners swear by them, arguing that they offer protection against sunburn, insects, and other environmental factors. But are these claims truly beneficial for your horse, or could it be counterproductive?
There are several factors to consider when deciding whether to rug your horse in summer. From the breed and coat type to the climate conditions, choosing whether or not to rug your horse can be a nuanced decision. This article will explore why some horses benefit from wearing rugs during the summer and when it’s better to leave them without one.

While it may seem counterintuitive to put a rug on a horse when it's hot, there are several reasons why summer horse rugs are used. Some owners believe that rugs can serve as a form of protection, making summer more comfortable for their animals.
One of the primary reasons horse owners choose to use summer rugs is to shield their horses from biting insects such as flies, midges, and ticks. These insects can be especially prevalent in warmer months and can cause irritation or even lead to disease transmission. A fly rug or summer rug offers a lightweight layer of protection, helping to keep these pests at bay without trapping excessive heat.
Another reason people opt for summer rugs is to protect horses with lighter coats or pink skin from sunburn. Just like humans, horses with sensitive skin can suffer from sunburn if exposed to too much direct sunlight. In particular, white horses or those with large areas of exposed skin may be at risk for UV damage, which can lead to discomfort and long-term skin issues. A lightweight summer rug helps to block UV rays and keep your horse’s skin protected.
Though there are valid reasons for using summer horse rugs, it’s essential to address some of the concerns that come with their use. Not all horses require a rug in the summer, and improper use can lead to unnecessary discomfort or even harm.
The biggest concern with using rugs in hot weather is the risk of overheating. Horses are large animals with a considerable internal body temperature, and they rely on sweating to cool down in the heat. If a rug traps moisture or prevents natural airflow, it could cause the horse to become overheated, leading to heat stress or dehydration.
Choosing the right rug from Bowhorse ensures that your horse is well-protected but also able to regulate its body temperature. Their summer horse rugs are designed with ventilation in mind, allowing air to circulate freely to avoid overheating.
Some rugs may cause a horse to sweat excessively, even in the summer months. This is particularly true if the rug is too heavy or made from non-breathable materials. Horses are better off without a rug if they are able to naturally regulate their body temperature.

Despite the potential downsides, there are several clear benefits to using summer horse rugs, particularly when used correctly.
As mentioned earlier, one of the greatest advantages of using summer rugs is the protection they offer from insects. Insects such as horseflies and mosquitoes can cause pain and even spread diseases. A lightweight fly sheet is an excellent tool for keeping these pests at bay, providing your horse with a much-needed layer of protection during peak insect season.
Products from Bowhorse are designed to cater to this need, with fly rugs that help prevent irritation while still allowing horses to enjoy the outdoors.
For horses with lighter coats or more exposed skin, sunburn is a real risk. A summer rug can act as a physical barrier against harmful UV rays, helping to prevent the painful and damaging effects of sunburn. This is particularly important for horses that have light-coloured manes, tails, or coats, which are more prone to sun damage.
The Orion Summer Rug provide great protection against UV rays, ensuring your horse’s skin remains healthy and safe from sunburn.
There are also several circumstances where using a summer horse rug is not advisable. Understanding these conditions can help ensure the comfort and health of your horse.
Some horses are naturally adapted to warmer climates and may not require a rug at all. These horses have a thin, short coat that allows them to regulate their body temperature more efficiently. For these horses, wearing a rug could restrict airflow, preventing them from cooling down naturally.
It’s important to remember that summer horse rugs are only beneficial if they are well-suited to your horse’s needs. If the weather is particularly hot or humid, adding a rug to your horse could increase the risk of overheating. Horses rely on their natural cooling mechanisms, such as sweating, and covering them with a rug can interfere with this process.
If you decide that a summer rug is necessary, choosing the right one is crucial to ensuring comfort and safety for your horse.
When selecting a summer rug, consider the following factors:
Material and Breathability: Look for rugs made of breathable materials like mesh or lightweight cotton. These fabrics allow air to flow freely, preventing overheating while still offering protection.
Size and Fit for Comfort: A properly fitted rug will not only provide comfort but also allow your horse to move freely. Ensure that the rug is the correct size and does not restrict the horse’s movement or cause irritation.
Products such as Hydra Hybrud Rug are ideal, as they focus on breathable fabrics that allow moisture to evaporate, keeping your horse comfortable.

Breathability is key when choosing a summer rug. Mesh or thin, perforated fabrics allow for maximum airflow, which is essential in preventing heat build-up. Avoid heavy, insulated materials commonly used in winter rugs, as these can cause your horse to sweat excessively, particularly in high temperatures.
An ill-fitting rug can cause chafing or discomfort. Ensure that the rug is the right size for your horse and fits securely without being too tight or loose. This ensures your horse is comfortable and can move freely.
Even without a rug, it’s essential to ensure your horse remains cool, hydrated, and comfortable during hot weather. Here are a few tips for looking after your horse when a rug isn't necessary:
If you choose not to use a rug, there are still ways to help your horse stay cool. Providing access to shade, using fans, or offering frequent baths can help to cool your horse down. Additionally, providing fresh, cool water is essential to keep your horse hydrated and comfortable.
Make sure your horse always has access to plenty of fresh water, and ensure that there is a shaded area where they can retreat from the direct sunlight. Horses can easily become dehydrated in the heat, so it's important to monitor their water intake.
So, should you rug your horse in the summer? It really depends on your horse's needs, the climate, and the type of activities your horse is involved in. If your horse is sensitive to the sun, has a light coat, or suffers from insect bites, a summer rug can offer great benefits. However, be mindful of the risks, such as overheating, and always choose a rug that is breathable, comfortable, and suited to your horse’s needs.
If you’re still uncertain about what is best for your horse, you can always consult with a veterinary professional or an experienced horse care expert. In the meantime, Bowhorse offers expert advice and high-quality products to help you make the best decision for your horse's summer care.
