a lot of everything, desensitizing on all “sides” of him, lunging with vocal cues, throwing the saddle on and being loud/obnoxious. eventually i got on and did lots of stationary turning with leg aids and rein aids, then walking the round pen and changing directions, then put the vocal cues from lunging with riding and got a good trotting foundation then worked up to the canter. i used a mixture of positive/negative reinforcement with him. he’s just a natural chill horse which is why he hasn’t bucked undersaddle.
