I have had casual advise from friends that 'the best thing to do id to keep him moving' (he is fine when he is working, flat and over fences). I decided to look it up today to find out what exactly is wrong with him. I found this article:
Sticky or Locking Stifle - Cause and treatment
It states that it is most often seen in young horses, my horse is 12 ?
Any advice? Or anyone have any experience with this.
And before you say 'call a vet' all the vet can do is confirm what it is, I know whats wrong with him.
