I’ll preface this by saying that for many reasons (including equine ones) I’m feeling very fragile at the moment so please be kind. Last year I got my first horse - a very sweet-natured 15.1 cob. All went well to start with - I’d tried him twice in the school and out hacking - he did a bit of a spook but it was nothing I couldn’t handle and he was basically an ‘energy conserver’. He was quite green for his age but my daughter was happy to school him for me. After a few months we started to have the odd incident - he got his head underneath his lead rope when he was tied up on the yard for a couple of minutes, panicked, reared up and fell heavily against the stables, he started getting very nappy in the school and would suddenly take off out on hacks - it felt like he was panicking, one minute he’d be pootling along on a loose rein then suddenly he’d be charging down the road with no obvious trigger. After one incident dd decided to take him in the arena to see what was going on - he was fine for 20 minutes then she picked up canter and he was off in a blind panic - eventually she managed to pull him up but she said she didn’t feel safe on him and didn’t think I should ride him again. We had the vet out - he had the equivalent of a vetting but there was nothing obviously wrong. He’d had clean leg x-rays when I got him and we x-rayed his back (clean) and scoped for ulcers (clear). The vet said his gut feeling was that it was something that was causing him sporadic bursts of pain, probably an abnormality in one of his facet joints but it was very difficult to diagnose and not easily treatable so his recommendation was to retire him. He’s been mooching in the field since September but he’s been getting increasingly bad tempered with the others (it’s a stable herd who otherwise all get on really well), bargy to lead and breaking through fencing (post and rail and electric rope). He’s not cantering or playing with the others (will do a few strides of disunited canter but quickly pulls up) and generally seems quite unhappy. They have 24 hour turnout in large, undulating fields with natural shelter, hedgerows to browse, constant company for mutual grooming, safety and friendship so all the others are really happy and relaxed. I don’t know what the best way forward is now and I’m feeling very sad and lost about it. Any advice?
