Another common condition you should be on the look out for with your horses is Greasy Heel. Also if you have used Heritage Downs Cream we would love to hear from you.

While monitoring the health of your horses you should be on the lookout for signs of Greasy heel (aka mud fever).

What is it?
Greasy Heel is an inflammatory condition of the skin (dermatitis) involving the lower limbs, particularly non pigmented skin (White socks). Lesions appear as scaling, crusting, and can be due to a number of skin conditions. Organisms that most commonly cause Greasy Heel include fungi, bacteria and mites in horses with feathering at their fetlocks.

How does it occur?
A number of environmental conditions can by key ingredients for Greasy Heel, however horses with white legs and feathered fetlocks appear to be particularly susceptible. Favourable conditions for the development of Greasy Heel include:
• constant or repeated exposure to moisture eg. swimming, wet bedding, muddy paddocks from wet weather
• low heel conformation
• insect bites on the lower limbs
• abrasions from loose surfaces eg. gravel
These conditions reduce the effectiveness of the skin as a barrier to organisms allowing them to invade into the skin.

What does it look like?
Early in the disease, Greasy Heel appears as a mild sore with swelling and reddening of the back of the pastern. Hind limbs tend to be more frequently involved, however lesions can occur on all four limbs. With progression of the disease, numerous scabs and/or crusts may form, causing matting of the hair. If left untreated the infection may extend up the limb and secondary infection may occur, resulting in pus discharging from the area and more severe swelling of the limb. In horses with feathered fetlocks, lesions tend to be more severe and occur over a larger area, whilst lesions tend to be smaller in short haired horses.

.Treating the Greasy Heel Condition in Horses

In it's early stages, Greasy Heel is not painful, but may cause some discomfort to the horse. However, if the lesions are not treated and allowed to progress, they may become pruritic (itchy) and lead to scratching, further trauma and lameness.

What can I do, as an owner, to treat Greasy Heel?
The most important aspect of the treatment of Greasy Heel involves identifying the problem.
Steps to reduce and treat Greasy Heel include:
1. Keep lower limbs dry
2. Clip hair and clean the affected areas
3. Soak the affected limbs for 10 minutes with water
4. Remove all scabs with a soft cloth, but DO NOT cause bleeding as this will lead to further scab formation. Scabs may need to be softened before removal using chlorhexidine solution or an iodine soak to prevent this. Other softening agents such as manuka honey or simply warm water may also be used. Once softened, remove scabs by rubbing lightly with either a betadine or chlorhexidine solution, or medicated shampoo.
5. Once removed, hose off solution with water and towel dry
6. Apply antiseptic ointment over affected region, and lightly bandage to prevent contamination and sunlight exposure.
7. Repeat steps 2-5 every one to two days.

Does this condition require veterinary attention?
If Greasy Heel is found in its early stages, the above steps should be followed and any changes noted. If the lesions/sores worsen even with treatment, or any severe signs such as lameness, cracking or bleeding are present, you should seek veterinary advice. The vet may need to assess the horse to direct appropriate therapy such as antibiotics.

How long will it take to heal?
Unfortunately Greasy Heel can be a persistent disease and appear as though it is not responding to treatment. Don't give up, treatment may need to be continued for weeks and possibly months. If the environment is kept clean, dry and the area is regularly cleaned, improvement should be seen as the disease is self limiting in most horses.

How can Greasy Heel be prevented?
Prevention is the best cure for Greasy Heel. The best prevention can be achieved by housing the horse in a clean, dry environment. The lower limbs should also be monitored for any signs of reoccurrence such as swelling or reddening of the skin so therapy can be started early in the disease process.

Heritage Downs provide a very effective treatment cream – see details here.

To remove scabs Olive oil leave half hour apply again leave half hour then wash warm water little washing liquid and rinse. All scabs come off to clear skin them treat with which ever treatment you choose. Muddy buddy is good and neem oil too . Not together

I have had success treating mud fever (greasy heel) with a daily application of Neem Oil. Neem Oil contains antibacterial and anti fungal agents,so you simply paint the clean affected area with the oil covering the entire foot if need be. The oil repels water and mud, while the properties of the oil start healing the condition! Less than a week to clear a stubborn case! Only downside- the oil stinks!

If you take the same approach suggested by Dian above for cleaning and then apply anhydrated wool-fat (Priceline, pretty cheap) as the slave, the water stays out and the scabs soften by themselves. Looks ugly because everything sticks to the wool-fat but you just clean it off again the next day and repeat. Most effective treatment I've ever used.

If the affected area is sore, try wrapping a clean soft cloth ( I use old face flannels) soaked in a mix of warm water and medicated wash around the leg and leave on for at least 1/2 hour to 1 hour. This will soften the scabs. Dry the area gently with a clean dry towel in a small circular motion, this will start to lift the scabs and remove the grease. Repeat the exercise until the area is free of scabs and grease. Then apply treatment cream. It takes a while but this method is a more gentle way of removing scabs than scrubbing and the horses seem to find the warm water/wash soothing.
