In the free-roaming horse, it hardens into a callus consistency with a near-smooth surface. [citation needed] For good health, the horse requires dry areas to stand. If chronically exposed to bacteria, for example standing in manure, the frog will develop an infection called thrush. [2] The frog is anatomically analogous to the human fingertip. [3]

The skin is shed every few weeks. It usually splits down the middle of the back and across the belly, and the frog pulls its arms and legs free. The sloughed skin is then worked towards the head where it is quickly eaten. [61] Being cold-blooded, frogs have to adopt suitable behaviour patterns to regulate their temperature.
Heels are separated by an elastic, resilient structure named the 'frog'. In the palmar/plantar part of the foot, above the heels and the frog, there are two oval bulges named the 'bulbs'. When viewed from the lower surface, the hoof wall's free margin encircles most of the hoof. The triangular frog occupies the center area.
