What is a concave profile in horse terms?

A concave profile in horse terms refers to a head shape where the line of the profile curves inward, tapering from the forehead down to the muzzle. This profile is often characterized by a slight dip or curvature in the nose, creating a more refined, delicate appearance that is often desirable in certain horse breeds, particularly those that are meant for specific disciplines such as dressage or show jumping. This profile can suggest a more manageable and elegant horse, which is why it is often favored in horses that are showcased for their aesthetic appeal.

The other options describe different head shapes that do not adhere to the definition of a concave profile. A flat and broad head suggests a completely different structure, lacking the inward curve that defines a concave profile. An outwardly projecting head would indicate a convex shape, opposite to concave. The description of a head with a large forehead does not necessarily imply a concave profile and can refer to a wide variety of head shapes. Thus, a tapering head that fits the description of a concave profile is the defining characteristic being sought in this context.
