hi horseslave, yep it is Y and we are making progress but sometimes it seems soooo slow. We lunged him today with and without boots and I learnt heaps, like the footfall sequence in his transitions from canter to trot tend to be wrong as he doesn't want to put his inside fore under too much stress, I don't quite fully understand yet which is why that might not totally make sense. My instructor thinks that if there is anything then it is too subclinical to get an unambiguous diagnosis but I think for peace of mind I have to give it a shot. Though poss. post Crimble.
