We've had vet, back person (three times!), new saddle, teeth all done. No sign of lameness. He's just stopped wanting to jump :-( dd's trainer says he may have lost confidence - god knows why as dd is a good rider and we've kept him in his comfort zone. We bought him as he'd jumped round 1m tracks and qualified for many championships. Dd was eliminated from a 70cm at the weekend :-(
I could get my more experienced dd to ride him but obviously don't want to push him if he's in pain - but he shows no sign of pain other than the stopping. If anyone has any advice I'd be really grateful.
