Is he in any pain from back/saddle?
I had this issue with my mare in December after she had 10 days off with an abcess.
Made sure she had no pain (she did a minor rear.. or three) and then lunged her, lunged her and lunged her. MADE her move forwards. I then got on attached to a lunge and my trainer lunged us.
Worked, then took us off, and it stopped. Was a HUGE respect issue. I was too scared to touch her with a crop as a previous time I had accidently brushed her with it and she went beserk.
I had to in the end, and I had no issues.
Check for pain
If there is none, more ground work is required as it would appear to me that its a lack of respect.
Have you got access to a trainer?
