I know good things come with time, but what are something that I can do to really hep Rocket get a top line? I don't have any hills around me, and lunging him is usually just asking for him to be super hyped up the rest of the day. I heard about "tickling" there tummys to get them to arch their backs to help develop those muscles. Does this really work? I also know that lots of balanced up and down transitions help as well. I finally have a saddle that I think fits so hopefully he will be more willing to round up. Anything else I should be doing?
