Hello, I have an on aagain-off agin issues with my 14 year old horse. Sometime I can catch her in the pasture and other times she walks away from me hiding behind the other horses,trotting from one end to the other. It's very frustrating and often I have to get help to catch her. Someone told me that if you keep them running eventually they will stop-she is an endurance horse-this could go on all day! I only approch her when she has stopped moving,but starts to trot away as I get closer.Does anyone have any Ideas why horses do this every so often and what can I do to stop it?
