Courtney King-Dye-Dye works with a new client and horse competing at Fourth Level.  They have let her know that the horse is tough in the mouth, and Courtney has them start by explaining an effective half halt while riding the volte at the walk.  She has the rider add the leg to keep him from slowing down with the half halt.  They show good examples of staying uphill in the canter with the half halt.  Courtney helps her keep the canter jumping and up as well as the trot after the canter.
