The last few rides have gone well and I have definitely gotten to know Caesar much better. I am more relaxed and confident and was starting to think “hey this might not be so bad". With that being said I ran into a little problem today. I took him out for a ride in the pasture he is used to and he stumbled a few times then fell to his knees. I just knew I was going to fly over his head but managed to stay in saddle. I started to head back to the barn and he stumbled twice again, so I dismounted and walked him the rest of the way so he or I wouldn’t get hurt. I examined his hooves and he seemed ok to my untrained eye. I am really worried about this, any advice would be greatly appreciated.
