For probably over a year now I've been working on Dancer's jog. Usually he wants to try and give me a huge trot. My instructor calls it his Warmblood working trot. Well, now he has decided to be a punk and only jog!!! No matter how much I squeeze, cluck, overexxagerate my posting he won't go any faster!!! Any tips? I would really like him to be able go from jog to fast trot depending on my non-posting or posting.
