When talking to non-hobbyists, I find it’s usually easiest to describe live showing as a shrunken down version of the real thing. However, this comparison only works to a point. Not all breed associations offer “halter” classes at their shows and those that do each play by their unique set of rules.
And then there’s fashion. A written breed standard is rarely amended, let alone substantially altered, but the current aesthetic in all halter shown breeds appears to be in constant flux. In some breeds, halter bloodlines have become so specialized they’ve virtually become a breed within a breed. For illustrative purposes, I’m going to use the Quarter Horse as the most dramatic example of this split, but the same issues apply to a number of breeds including other stock breeds, Arabians, and Morgans. Cutting, reining, roping, pleasure, hunter, racing, and halter have all split out to varying degrees within the AQHA, but no type is excluded from a model horse halter class.
When I judge a model QH class, I know I have options on how I can approach it. The first option is to judge it as a real world halter class and choose horses that best represent this physical type:
