Need help in getting horse to go from walk to canter. Have first horse show in two weeks. Am showing in the novice amateur in AQHA Western Pleasure. Horse is finished show horse with ROM in Open Western Pleasure. Works great with trainer but I can't seem to go from a walk to a canter without trotting. Trainer is trying to help...I just seem to have a mental block. NEED HELP FAST!!!! Just something to get me thru the 6 day show without making a complete fool of myself. Have been taking lessons for two months now and will continue after this show!!!! PLEASE HELP ME AS SOON AS POSSIBLE!!!! Thank you!
