Overview
If your horse has sweet itch, call the vet if the itching is severe, the skin is broken, or the problem isn't settling with your usual fly-season routine. Sweet itch is often linked to insect irritation, but similar signs can also happen with skin infection, parasites, allergies or other skin problems, so it can be hard to tell at home.
Things To Check
1. Check whether the itching is worse at certain times, such as at dawn, dusk, after turnout or after exercise.
2. Look for rubbed areas along the mane, tail, tail head, face, belly or ears.
3. Check for broken skin, scabs, crusting, heat, swelling or any discharge.
4. Notice whether the horse is stamping, tail swishing, shaking its head or struggling to settle.
5. Think about recent changes in turnout, stable time, bedding, grooming routine or insect pressure.
6. Check whether the problem is new, seasonal, or something your horse has had before.
7. Look at the horse's general behaviour and appetite, and whether it seems bright and comfortable otherwise.
Common Causes
The most common cause is sweet itch itself, which is usually a reaction to biting insects and can be worse in warm weather, around water or in the early evening.
Other common causes include simple fly irritation, rubbing from sweat or tack, dry or sensitive skin, and skin damage from repeated scratching.
Less commonly, similar signs may be linked to mites, lice, fungal or bacterial skin issues, or another allergy-type problem, which is why a vet may be helpful if it keeps coming back or looks different from usual.
What To Do
Start by reducing exposure to biting insects as much as you can with turnout timing, shelter and a consistent daily routine.
Keep the affected skin clean and dry, and avoid harsh washing or vigorous grooming over sore areas.
Try to note when the itching is worst, what areas are affected and whether anything seems to make it better or worse, as this can help your vet if you need one.
If the skin is only mildly irritated, gentle management and close monitoring may be enough for now. If the horse is rubbing hard, making the skin raw, or the signs are spreading, arrange veterinary advice.
When To Contact A Vet
Contact your vet if the itching is severe, the skin is broken or infected-looking, or your horse seems distressed, sore or unable to settle. It's also sensible to call if the problem is getting worse, keeps returning, or you aren't sure it is really sweet itch.
Your vet can help check whether the signs fit sweet itch or whether something else may be going on, and they can advise on a management plan for your horse's needs.
