Hi ! In a halter class the judge is looking for: good basic conformation, overall balance, correct legs, strong hindquarters and movement. In breed-specific situations, the judge is comparing your horse to the breed association’s official breed type description; in some cases very minute details (size of the eyes, for example) will be considered.
Many halter classes can be broken into two phases. One is the inspection phase, in which the judge examines one horse at a time and analyzes conformation and type while checking for any disqualifications. Each horse is also judged at the walk and trot in order for the judge to evaluate movement and way of going. The second phase involves returning to the "line up,” where each horse and handler wait while the other competitors are inspected.
Different shows and classes will have different pattern requirements. Some might want you to walk in for inspection and then trot away, some might require that all competitors come in trotting and then line up along the rail before inspection. Read and understand any posted patterns, watch any classes that are before yours, and listen carefully to instructions from the ringmaster or announcer.
Learn the specifics on how to show your breed or type. Some breeds, like Arabians, for instance, are shown in breed-specific tack and are positioned in a special way when standing in the ring. Some breeds are expected to be groomed differently than others (braiding, etc…) Find out what’s typical for your horse’s breed. Also, find out what you are expected to wear.Like all horse show classes, grooming is important, but it is particularly important for halter. While the judge isn’t necessarily "judging” your horse’s grooming, if all things are equal and two horses are both excellent examples, the one with the better grooming job just might edge out the other. Give yourself enough time before the class to bathe, groom, polish hooves, braid, or whatever is required.
Remember, you and your horse are being judged during the entire class! Don’t stop showing just because you’re in the lineup of a very large class and other horses are being inspected.
Good Luck !
