The '''wall''' forms the medial, lateral and dorsal aspect of the hoof and it can be further divided into the '''toe''', '''quarters''' and '''heels'''. At the heel the walls reflect back on themselves at a point called the '''angles''' and in doing so forms the '''bars'''. The bars, although moving cranially, gradually fade along the edge of the frog and never actually meet.

The '''frog''' sits between the bars and has an apex facing distally, with 2 crura flanking a central sulcus. Between the crus and bar of each half of the sole lies the '''collateral sulcus'''. Opposite the apex, the frog expands forming the '''bulbs of the heel'''.
The '''frog''' is a wedge-shaped structure which sits between the bars and has an apex facing distally, with 2 crura flanking a central sulcus. Between the crus and bar of each half of the sole lies the '''collateral sulcus'''. Opposite the apex, the frog expands forming the '''bulbs of the heel'''. Usually, the frog contributes to the weightbearing surface where it functions as a shock absorber.

===Sole===
The '''sole''' is the area distal to the bars and apex of the frog enclosed by the hoof wall. The area where the bars and wall enclose it is known as the '''angle of the sole'''.
