"We sometimes overlook and become complacent about the everyday environmental effects on domesticated horses’ feet. Hooves are affected by wet or dry climates, fields, stalls, run-in sheds, etc. Thin soles are directly associated with a wet environment and are sometimes overlooked until they become a problem."
HOW CAN I TELL IF MY HORSE HAS THIN SOLES?
The first indication of this condition is shortening of your horse’s stride and his reluctance to be ridden over stony terrain. More often than not, a horse will veer to the grass verge because he is more comfortable walking on this softer and more giving area. This is a true signal of soft or thin soles; be intuitive and learn from your horse as your horse knows best!
