In this video you learn how to teach your horse how to pick up your hat. The host says that horses are mouthy and they tend to pick things up such as an empty food bucket, they'll pick up paper, they'll pick up things that are curious. He says that horses are fairly easy to teach this. He says that his horse used to pick up his grain bucket when it was empty. He says that when his horse would pick it up he would say hat and give the horse a treat, and after a while the horse would use this command to pick up things considering the horse is expecting a treat. However don't give your horse a treat without giving you the hat in your hand, and you can practice by throwing your hat in different directions.
