Are you sure it's just wrinkles, sweat, and gnats making him raw? This type of injury is more typically caused by your girth is rubbing him raw.
Galls are created when the girth pinches and rubs loose folds of skin. They typically occur under one or more of the following conditions: |
Continued girthing will worsen the damage and, no doubt, the horse's attitude about being ridden. If you must ride the horse before the gall is completely healed, armor the sore with a thick layer of ointment, and use a fleece cover over a soft girth. A protective fleece girth cover may work well as a preventive strategy, but it has to be cleaned often to maintain its cushioning properties.
- The horse's conformation -- usually an upright shoulder, "mutton" withers and a wide torso -- causes the girth to stay very close behind the elbows no matter where the saddle is initially placed.
- A recent tack change or a new saddle may position the girth differently, causing irritation.
- The horse is not well conditioned for his current work, leaving the skin vulnerable to damage.
- A dirty, stiff or ill-fitting girth concentrates friction on the sensitive, mobile skin behind the elbows. Treat girth galls with careful cleaning and application of a thick, protective ointment, such as Ichthammol or Desitin. Then, stop riding the horse (or ride him bareback) until the sore heals completely, which can take as long as three weeks.
