A few years ago I would have agreed with you. My thinking has shifted as I’ve seen more KS cases. I’ve realized those I wrote off as asymptomatic were symptomatic, I was just looking for the wrong symptoms. They didn’t bolt or buck or misbehave - symptoms most people associate with symptomatic KS. There are other symptoms that are not necessarily behavioral, like discomfort being mounted, girthiness, prolonged ulcers, toe dragging, hock and/or SI issues, etc. The list is long.
I would stress that it’s important to get the right angles on rads… Use a trusted source to do additional diagnostic imaging if you[g] are looking at a horse with KS findings on PPE.
My comment above (and this one) was not directed at Benchmark Sport Horses - just more of a general observation. If anyone wants a glimpse into what owning a KS horse is like (and whether there are truly any asymptomatic KS horses), there is a large group on FB called “Horses With Kissing Spine” and the posts are sobering.
