Consistent insect management, including fly sheets, masks, boots, fans, and topical insect repellent products like fly spray, may help reduce reactions in susceptible horses.Whensensitiveskinned horses are bitten by insects, the resulting itching and inflammation can lead to rubbing, scratching or biting. This trauma weakens theskinbarrier, providing an entry point for bacteria and increasing the risk of secondaryskinproblems, including rain rot and staph infections.Choose Fly Spray CarefullyFor somesensitiveskinned horses, fly control presents a catch-22: Insect bites trigger irritation, but the fly spray used to prevent them may also cause a reaction. Certain horses may besensitiveto the active ingredients or carriers used in a particular formula, including the ingredients that distinguish water-based from oil-based fly sprays.Water-based fly sprays are typically lighter, dry more quickly, and leave less residue, making them a useful option for horses that haveskinreactions to oil-based products.Oil-based formulas often last longer and resist sweat or light rain, but they can leave an oily buildup that traps dirt and sweat against the coat, which can lead to secondaryskinconditions or allergic reactivity.Regardless of the formula, patch-test every new fly spray on a small area for 24 to 48 hours before applying it all over the horse. This can prevent a localized sensitivity from becoming a widespread reaction.Stop using any product that causes redness, swelling, hives, itching, or hair loss, secondary infections, and hose the horsesskindown immediately if they do react. Because frequently rotating products can makeskintriggers difficult to identify, introduce only one new product at a time.Sweat, Humidity and SummerSkinFlare-UpsSummer heat, humidity and frequent insect exposure can keep asensitivehorsesskindamp and irritated for hours.After riding or turnout, remove sweat and dirt from high-friction areas such as beneath the saddle, girth, mane and between the hind legs. Hose off, bathe, or wipe the coat as needed, then allow it to dry completely before applying fly sheets, fly boots, etc.Check theskinregularly for early crusting, scabs, itching, swelling, or hair loss in the summer, especially during very hot and humid weather. Persistent moisture from humidity, insect bites, and rubbing can weaken theskinbarrier and contribute to rain rot or secondary bacterial infections.Clean grooming tools, tack, and saddle pads regularly to prevent sweat, dirt, product residue, and infectious organisms from building up and further irritatingsensitiveskin.The post Summer Survival Guide for Horses with Extremely Sensitive Skin appeared first on Horse Illustrated Magazine.
