Peter had the Chiro out to look at him and it turns out that his left hip as about 2 inches out of alianment and tilted down than the righ hip, she said its an old injury probably from an accident (like falling over in the paddock) and she said that what most likely caused his kissing spine. Had to go on a 'recovery' process with him, 2 weeks walking only to the left, 3rd week trot, 4th week pole work, 5th week canter, 6th week working normally. So probably going to miss at least the first 2 dressage shows, but as long as Peter comes ok im happy. He's not really supposed to be running around and bucking etc until the 6th week, but he's only 6 and been dying to play, and he runs around in the paddock every morning and it doesnt seem to have done any damage.
Anyway he's been moving fantastically since then, he's got a 'bigger' trot now, swinging more at the hips, building muscle etc etc.
He looks really awkward in these lol
I Love his expression in this
