Anyone have any ideas on how I can help my friend, she has just bought a new horse 17h Irish draft. He seemed perfect but she's had a couple of incidents that has made her really anxious about riding him, to the point where she doesn't want to get on him. I've been making her ride him just for short hacks of about 25 minutes but she won't even trot him. I've been through the same thing so I know how she feels but I'm giving her all the support I can and so is the yard owner. I just don't know what else to do , she is normally a very competent rider.
