I have been working with my horse to do some of the Parelli games as we have had some rearing issues appear under saddle. He has been thoroughly vetted x rays, scoped, bloodwork etc, all healthy. When I put the whip still on his side where my leg would be to yield his hind end he will get generally displeased. He will start to flick his skin, quickly yank his head around to touch the whip, tail swish, ears back. So far I have been doing a lot of friendly game before and after asking him since I worried he was fearful of the whip since I discovered that Whenever the whip is still on him anywhere he has the same reaction. But now I am wondering if I shouldn’t be releasing pressure until he moves over and stops with the negative reaction. Currently I have been stopping when he moves over and then playing friendly game again as he seems almost offended. I am not pushing at all with the carrot stick just letting it be still. Interestingly enough he has a similar reaction to when you put your leg on him under saddle to ask him to move on and he will not and will rear if you continue. ( he was fine for the first 6 months of owning him but he is off the track so perhaps he has more baggage than I originally thought!) any advice would be great!
