Champ is Testing Me

Horses are funny. So Champ is a bit pushy (testing me) so I started doing ground work him this week. Basically just doing Clinton Anderson's first 5 steps to start with. So today, I came home and went out to see them and he was fiesty, running around winding his head, you know the play move they do. When I went over to pet him, he ran away. So I petted Cody and the others, then went inside. I came out later, and he ran away again. Like... "NO NO you'll never get me!" So I ignored him and petted the others, then started doing chores. I turn around, and he's following me around. Like.. "What? You don't want me? WASSUP with that?"
