Hi everyone! I am new to this forum so I hope I'm not posting this in the wrong section. Anyway, I have been taking horseback riding lessons for about 8 months now. Things have been going well until recently. At my past four lessons, my horse has been very stubborn and is refusing to trot. If I nudge him gently with my heel, he won't move. If I apply more pressure he starts to buck and kick. I know there is nothing physically wrong with him because a vet has checked him out and my instructor who has been riding for over 30 years always makes sure the saddle fits properly. I've tried using a crop these past few times to get him to trot, but even if I just lightly tap him with it, he starts to either kick or throw his head around. Other people ride this horse and don't seem to have this problem. Like I said, I haven't had problems getting this horse to trot until these past four lessons. I do everything my instructor tells me, but nothing seems to be working. It's very discouraging, especially since things were going pretty well until now.
Do you have any tips or advice on how to get this horse to trot again? Thank you!
