The signs of sweet itch

Rubbing usually starts on the mane and tail and then spreads to the face, topline and rump. The area is rubbed bald. The skin may break and weep serum or even blood.

In severe cases a horse will also rub his legs, chest and belly.

If your horse has nothing to rub on (for example, if your paddock is surrounded by electric fencing), he may roll frequently or, when brought inside, rub frantically against the stable walls.

Over time, your horse may develop corrugation and thickening of the skin of the dock and base of the mane.
