Wild horses move more home. However, their activity is more uniformly distributed by the time of day and by the seasons, which strengthens the stingy layer of hooves. With home horses differently: they spend many hours in the stall, then work for a long time. They have to move around the paving stones, stones. An additional load falls on their legs due to the rider or wagon. Therefore, hooves are erased faster. The growth of a stratuminal substance does not have time to compensate for this, and animals have to be hired.
