That big horse of Molly and Ella showjumping is bilaterally lame behind. It has been for ages and the 3-legged video should be a huge wake up call to them. There is an issue there and they might laugh and think the horse is being dramatic, but it’s going to come and bite them on the rear soon enough. It’s already having the odd stop and you can see why when you watch its hind end. The problem is the rider is too inexperienced to see or feel it.They used to deny that other horse had problems and said it was behavioural then all of a sudden found out it did have physical issues after all.
