So last night for my lesson, my trainer brought out her horse Chief whom I have ridden on trails for our cantering lesson. This helped me relax more, though I was still nervous. We did some riding under bridle at walk and trot and did good. He did break to a canter once, not sure if it was my fault, but he immediately stopped when I tensed up, he felt me bouncing and I asked him to whoa. We worked on trotting a bit more, then went to the lunge line for the canter. It was scary for me, though only psychologically. Both my trainer and Chief were very patient and it was a great experience! I'm excited that I finally INTENTIONALLY CANTERED! I have a long way to go in relaxing and overcoming my fears but I'm looking forward to my journey with the 2 of them and know I can trust them which tremendously helps!
