Head

This should appear to be in proportion to the rest of the body, and the ears should be alert and pricked. A horse should have a broad and flat forehead — a bulging forehead is thought to indicate bad temper and unpredictability — with large, 'kind' eyes set well apart to allow for good peripheral vision.

The nostrils should be large enough to allow for maximum intake of air, and the mouth should be neither too long, nor too short.
A horse with a very small mouth may be difficult to fit bits to, and a horse with a long mouth can often be strong and a 'puller.'

The incisors of the top and the bottom jaw should meet exactly at the front of the mouth, with the top jaw somewhat wider than the bottom jaw. There should be at least a fist-sized space between the two bones of the lower jaw, indicating unrestricted room for the start of the respiratory tract.

The head should be 'well set' to the neck, meaning that the horse should not be thick in the jowl and gullet region, which would restrict flexion. The neck should be long enough to allow for 'a good length of rein,' with a well-developed top line and a gentle curve from the withers to the poll.

As a rough guide, the length of the neck should be equal to one-and-a-half times the length from the poll down the front of the face to the lower lip. The neck should be 'well set' to the shoulder, being neither too low nor too High.
