Yesterday afternoon my 16 y.o. son was working with his dog on walking fetch. I was observing and giving unwanted advice. This training session was taking place in our pasture where we keep three Quarter horses. During the training session one of the horses walked over and picked up one of the bumpers (by the rope) and ran off with it! The horse only ran about thirty yards before dropping the bumper. Me, my son and his dog all stood there watching in amazement!
