He has improved, I can even tell that much from the shaky camera :)
He still is tossing his head and throwing himself into his right lead departure from the walk. But his lead changes are much cleaner, good job!
He is still half-assing his stops but still better than the first video :) I don't think he is taking you serious when you ask for them.
I know the one spin in the pattern sucks especially after backing! This is where preparation is so important to set him up to do it correctly.
He still has the habit of stepping behind when you are turning to the right. It is very important to know where his feet and weight is at and adjust accordingly.(especially after backing) He needs to learn to cross over in front of the right foot with the left front. It takes forward motion and shoulder control. And if I had to take a wild guess I bet he likes to lead with the right shoulder given that he likes to tip his nose out, toss his head and lead with that shoulder with the lope departure in that direction and the way he turns around.
Again, great improvement, in my opinion,
Good job Mango!
