I just used one today for the first time and had a good experience. I want to train my horse to fetch...lol. In just under an hour, I was able to train him to go to the object that I threw and put his nose on it. I used a small frisbee-like thing and a small pylon.
Step two will be to get him to pick up the object and step three will be to get him to bring it back. All the while, I will phase out the food treat and replace it with only a click.
Has anyone ever taught their horse to fetch?
What other fun tricks does your horse do?
