A U.S. Equestrian Federation-generated protest measurement of two ponies at the Kentucky National Horse Show on Sept. 15 has reignited the debate surrounding pony hunter sizing.

Using a rule that’s been in the USEF Rule Book for years, a USEF steward selected two winning ponies—one medium and one large—on the last day of competition for a measurement check to ensure each was within his allowed height section. The ponies had an hour to prepare, and each pony measured into the correct section.
