Red-1
I used to be decisive, now I'm not so sure...
I look back at this and realise he is lame now but just clueless at the time and it was a slow one - just a gradual loss of performance and one day finally obvious. He was always a lousy sjer but some of that was training, me being clueless and him being spooky and tricky. Easy to blame your riding a lot of the time. This doesn’t help with identifying issues though as his behaviour was consistent. He was tricky in the mouth and it got worse which I now look at as a flag, had irregular muscles behind (I never used to look) which is also now a flag for me I stand on a chair and check them regularly. I also video lunge them every few months and keep the videos to compare as sometimes not obvious if you see them everyday. I am much more concerned about posture now and I have things I do regularly to check whether they are even in how they move like turning a tight circle in hand and looking at the cross over behind and how easy they find it.
That is a heck of a lot sounder than most horses that are for sale. He looks basically sound there, with the odd falter when changing something, but it is barely discernible and, with it also being on grass, I would have gone to view had he been for sale as I would have thought it would be possibly just uneven ground.
I used to teach, and had to sack the occasional client for lameness that they didn't want to know about and investigate. One who had a vet/physio involved but they said to continue work where I said no. I did a video the last time I went, to show the owner why it was a no, so they could go back to their professionals.
I also taught a couple who had nice horses who were destined for light hacking but were not sound for arena work. I would do minimal lessons to get them safe enough to enjoy their light hacking so the horse could live a useful, steady and happy life. I would tell the owner that this is what we were doing, have the vet involved and sometimes pain relief just to get horse/rider on the same page.
