Hoof Facts
Since horses evolved in arid conditions, the exterior of the natural hoof is normally tough, dry and quite capable of withstanding the abrasion and impact from rough terrain.
When horses are taken out of their natural environment and placed in humid and/or wet conditions, some will cope with this change better than others. In many cases, however, the hoof wall and sole frequently become overly moist and soft, wearing away quite easily. Since the hoof is less able to support the weight of the horse, shoeing becomes a necessity.
Horseshoes often add another dimension to the problem. The hoofwall was meant to be a solid structure from the hairline to the ground. Every time a farrier perforates the wall with a nail, another avenue for excessive moisture and harmful organisms to enter is created. This can soften and weaken the hoofwall and can cause the sole to collapse and flatten. The loss of efficiency of the hoof as a shock absorber can lead to bruising and make the entire foot more susceptible to infection from bacteria, fungi and viral infections such as thrush and white line disease.
