Update 25th October 2019, I had Sally Ede out to do some communication and healing Mojo, today was the second session and she said he was much more relaxed this time.
He still is protective of his hind legs but was better when I picked out his feet before Sally arrived. I did the fronts as they are near perfect now and he holds them up well. Liz did the hinds whilst I bridged and treated, he lifted the left one as soon as she bent down and touched it, the right he lifted as soon as she asked him, held it up with no snatching at all.
He has been on Cortaflex and Buteless for around 8 weeks now, and Sally says he need to strengthening exercises, I have been backing him over poles and trotting over them too.
Long reining is the next stage them Liz will have a few ridden lessons with Sally. Then I can hop on board and continue with the pole work too.
The trimmer is coming the first week in November so hopefully he will be happier to let her trim them all, as long as we go at his pace.
