I don’t allow Zum to grab at grass or trees while I am riding him. I cannot ride on a loose rein if Zum is grabbing for food. I think ahead and pull his head away from the things he wants to eat before his head reaches them. I impress upon him verbally that it is not acceptable to eat while being ridden. I tell him: ‘It is time to exercise, not eat!’ When it is time to eat, I ride to a grassy area and I tell him he can stop and eat. I want every ride to be enjoyable for both of us!
