Sweet itch or pruritus as it can also be known as is a nasty affliction that affects horses. It can have very unpleasant effects on the horse as it causes them to rub away their skin using whatever rough surface they can to give relief to the symptoms. They will also scratch and bite at the lesions caused by the irritation in an effort to relieve the constant pain that the condition causes. Horses have been known to cause injury to themselves and destruction to the stables and property around them as the itching is quite maddening. It can also render them unable to be ridden as they will refuse to take anything on the skin including a rider.
Veterinary science is attempting to come to terms and cure the condition, yet Sweet itch is still not clearly understood. However, it’s causes are known. These come from flies and midges, essentially biting insects. These intern lead to infections and certain allergies. These small itches build up over time to create a crescendo of discomfort for the horse which is unbearable. How a horse responds to the itchiness before it reaches a critical stage is known as the “pruritus threshold”. A horse may still feel the itching before this threshold is breached but simply not notice or some any outward signs. Lice, which still cause damage to the skin can easily infest a horse, as an example, but it is not until an infection takes hold that the pruritus threshold is exceeded, and the horse begins to manifest real signs of discomfort and anger.
