Can You Blanket a Wet Horse? Understanding Fly Sheets and Moisture Management
No, it is generally not recommended to put a fly sheet on a wet horse. While a brief covering might be acceptable in specific, carefully managed circumstances, doing so routinely can trap moisture, creating a breeding ground for bacteria and increasing the risk of skin infections.
Understanding Fly Sheets and Their Purpose
Fly sheets are lightweight coverings designed to protect horses from biting insects, harmful UV rays, and minor abrasions in the pasture or stable. They are typically made of breathable materials like mesh or tightly woven polyester or nylon, intended to promote airflow. The question, “Is it OK to put a fly sheet on a wet horse?,” isn’t a simple yes or no; it depends on the context.
The Risks of Covering a Wet Horse
The primary concern with covering a wet horse, especially with anything other than a specialized wicking cooler, is the potential to trap moisture. This creates a warm, humid environment under the blanket, which is ideal for the growth of bacteria and fungi. This can lead to several problems:
- Skin Infections: Rain rot and other dermatological conditions thrive in damp environments.
- Chilling: If the horse is already cold and shivering, trapping moisture without proper ventilation can exacerbate the situation, especially if the fly sheet itself becomes wet.
- Discomfort: A wet blanket can be heavy and uncomfortable for the horse.
When Might It Be Acceptable?
There are limited situations where covering a slightly damp horse with a fly sheet might be considered, but these require careful judgment and constant monitoring:
- Very Light Drizzle: If the horse is only slightly damp from a light drizzle and the fly sheet is exceptionally breathable, it might be acceptable for a short period.
- Emergency Sun Protection: If a horse is sunburn-prone and gets caught in a light rain while turned out in the sun, briefly covering them with a breathable fly sheet could offer some protection. However, remove it as soon as the rain stops or the horse is no longer at risk of sunburn.
- Use of a Cooler First: If the horse is actively being cooled with a cooler (a special blanket designed to wick away moisture), then a fly sheet could be used briefly on top to help keep flies off while the cooler is working.
The Ideal Approach: Drying Before Covering
The best approach is always to allow the horse to dry thoroughly before putting on any blanket, including a fly sheet. This can be achieved through several methods:
- Towel Drying: Use large towels to remove excess moisture.
- Air Drying: Allow the horse to air dry in a well-ventilated area, preferably out of direct sunlight and away from drafts.
- Use of a Cooler: A cooler blanket is designed to wick moisture away from the horse’s body, promoting faster drying. Once the cooler is damp, it should be removed and replaced with a dry one, or the horse allowed to finish drying naturally.
Alternative Solutions
If fly control is a concern while the horse is drying, consider these alternatives:
- Fly Spray: Apply a high-quality fly spray to repel insects.
- Fan: Use a fan to create airflow and deter flies.
- Shelter: Provide access to a shelter where the horse can escape flies and the elements.
Comparative Table: Fly Sheets vs. Cooler Blankets
| Feature | Fly Sheet | Cooler Blanket |
|---|---|---|
| ——————- | ———————————————– | ———————————————- |
| Purpose | Insect protection, UV protection, minor abrasion | Wicking moisture, preventing chills |
| Material | Mesh, tightly woven polyester/nylon | Fleece, wool, synthetic wicking fabrics |
| Breathability | Generally breathable | Highly breathable and designed for wicking |
| Wet Horse Use | Generally NOT recommended | Recommended for drying process |
Addressing Common Concerns
Understanding the implications of “Is it OK to put a fly sheet on a wet horse?” involves addressing some common misconceptions. The belief that a fly sheet will help a wet horse dry faster is often incorrect. While some fly sheets may allow for some air circulation, they are not designed to actively wick moisture away like a cooler. Covering a wet horse with an inappropriate blanket is like wrapping yourself in a plastic bag – it traps moisture and prevents proper evaporation.
Frequently Asked Questions (FAQs)
Can a fly sheet cause rain rot?
Yes, in certain conditions, a fly sheet can contribute to rain rot. If a horse is wet and then covered with a fly sheet that traps moisture against the skin, it creates an ideal environment for the bacteria that cause rain rot to thrive. Proper drying is crucial for preventing this.
Is it okay to put a fly sheet on a horse that is sweating after a workout?
Generally, no. Sweat needs to evaporate for the horse to cool down effectively. A fly sheet will hinder this process and can lead to overheating. Use a cooler to wick away the sweat, then remove it and allow the horse to dry completely before considering a fly sheet.
What is the best material for a fly sheet if my horse tends to sweat easily?
Look for fly sheets made of highly breathable mesh materials. These allow for maximum airflow. Avoid heavier, less breathable fabrics, even if they offer more protection.
How often should I wash my horse’s fly sheet?
Fly sheets should be washed regularly, at least every few weeks, or more frequently if they become dirty or soiled. A dirty fly sheet can harbor bacteria and exacerbate skin issues.
Can I use a fly sheet to protect my horse from sunburn?
Yes, some fly sheets offer UV protection. Look for those specifically marketed with a UV protection factor (UPF). However, remember that coverage may not be complete, so additional sun protection measures, such as sunscreen, may still be necessary.
What’s the difference between a fly sheet and a fly rug?
The terms are often used interchangeably, but generally, a fly rug might refer to a slightly more substantial fly sheet, perhaps with a belly wrap or neck cover for added protection. Both serve the same primary purpose: insect control and protection from minor elements.
My horse hates wearing fly spray. Is a fly sheet a good alternative?
Yes, a fly sheet is a good alternative for horses that are sensitive to or dislike fly spray. It provides a physical barrier against insects.
Should I use a fly sheet with a neck cover?
A neck cover can offer additional protection from flies, especially for horses prone to sweet itch or those with sensitive skin. However, it’s crucial to ensure proper fit to avoid rubbing or irritation.
How do I choose the right size fly sheet for my horse?
Measure your horse from the center of their chest to the point of their buttocks. This measurement will determine the appropriate blanket size. Consult the fly sheet manufacturer’s sizing chart for specific recommendations.
Can I use a fly sheet in the winter?
Fly sheets are not designed for winter use. They offer minimal warmth and are not waterproof. Use appropriate winter blankets for cold weather protection.
Is it OK to leave a fly sheet on my horse 24/7?
While fly sheets are designed for extended wear, it’s generally not recommended to leave them on 24/7, especially if your horse has sensitive skin. Regularly remove the sheet to check for rubbing, irritation, or signs of skin problems. Rotate blankets periodically.
What should I do if my horse develops a skin rash under their fly sheet?
Immediately remove the fly sheet and consult with your veterinarian. They can diagnose the cause of the rash and recommend appropriate treatment. Ensure the fly sheet is clean and properly fitted before using it again. You may need to switch to a different material or brand.
