A combination of bacterial and fungal organisms cause scratches after
they gain access to skin that is irritated. The sites that are commonly
affected are the heel bulbs and the folds of skin on the back of the
pastern area. Characteristics of horses with scratches are often oozing,
red, inflamed and cracked skin. The transverse folds of the skin in this
area are commonly affected by cracks which are red, irritated lines that
appear like linear scratch marks, earning them their name. Unfortunately
the problem is often made worse by the potions and remedies many owners
use to treat the condition.
