Well, I worked with Dakota again today and took him on a short ride at the end of our session wih my cousin and her mare that he -hates-.
Last ride with Dakota was horrible... he tried to throw me, attacked my cousin's mare, tried to attack my friends mare, etc...
This ride was very good! He was obedient, led the entire way without an issue, and ony pinned his ears and gave my cousin's mare a 'dirty look' twice... didn't try to kick, bite, etc... He was just exceptionally well behaved!
Though he did shake his head a little (I rode him in a snaffle, so it wasn't his bit). I think his wolfe teeth are bothering him a little. He has one completely in on one side and the other is coming in on the other side... I intend to have the teeth pulled and his and my mare's teeth floated before this month is up.
Sorry for cluttering up forum-space, just had to tell someone!
