Grease Heel in Horses

a thick mucouslike fluid will begin to emit from the affected area. This symptom is how the name grease heel was coined as it can appear greasy over irritated skin. The lesions may become crusty as the fluid dries onto the affected areas.
Granulomas
Left untreated the skin can become deeply cracked and eventually infected. Granulomas may develop in more serious cases. This type of scar tissue and equine cellulitis consists of inflammation in the deeper layers of skin resulting in heat and swelling in the legs.
Causes of Grease Heel
The same conditions that cause rain scald also cause grease heel microbes that thrive in mud and wet areas. Grease heel is typically caused by the same bacteria thats seen in rain scald cases but if its left untreated other bacteria can also infect your horse 1 The following are common causes of grease heel
Muddy outdoor conditions If pastures and paddocks are muddy it may be hard to provide a place where the horses hoofs and legs arent wet. When the horses legs are constantly damp the microbes that cause grease heel can thrive. Grease heel may be more prevalent in the spring when pastures are muddy from snowmelt and rain and again in the fall when the weather is wet.
Damp stalls Damp stalls are especially a risk if ammonia from urine builds up which can cause and exacerbate grease heel.
Sun exposure Horses with white legs and pink skin are more likely to be bothered by grease heel than darkerskinned horses. Sunburns irritate the skin which makes it easier for this condition to develop.
Living conditions Leg boots can contribute to the buildup of sweat which allows bacteria to develop in the damp area. Its essential for horse owners to fit leg boots properly and clean them thoroughly. t
Diagnosing Grease Heel in Horses
If you suspect that your horse may be developing grease heel schedule a veterinary appointment as soon as possible to properly diagnose the affected area and begin treatment. Your vet will likely examine the horse and determine whether its living conditions are the cause of the problem. If they know your horses history your vet may be able to complete the diagnosis with a simple examination but they may also test for bacteria. These tests typically consist of an acetate tape impression or samples from the horses hair that can be examined under a microscope 2
Treatment
Mild grease heel can be treated at home by brushing
