How many problems are you willing to work with, versus turning down the horses?
Here’s the short list:
Kissing Spine
Navicular changes
DJD
Eye issues
OA in any joint that affects your discipline
Pedal Osteitis
OA in the Cervical Spine
Club foot/feet
Healed fractures
Screws
Healed and rehabbed soft tissue issues
And the list goes on and weird things get added over and over.
Here’s the thing… we all know that you can find a horse that has a more clean vetting than others, but it doesn’t hold that the horse in question will have the brain, desire and dedication to doing the job you want to do. Secondary to that… people who “MUST” have the perfectly vetted horse are not themselves vetted for competency as a trainer/rider. So they can (and have historically) create problems where there were not any before.
If you have the rads that show KS, you have to disclose that. If you choose not to take rads on resale prospects just so you’re in the gray area of “Plausible deniability” that only works so well. Either the horse has KS and things start to unravel, or the horse doesn’t have KS and things start to unravel, or it does have KS and it goes well, or it doesn’t have KS and things are fine. If you’re a fan of 'The Big Bang Theory" this is essentially the Schrödinger’s Cat situation.
More often than not I would recommend neck and back rads in every PPE. Not to kill a sale, but to disclose what you know and let the buyers work with their team to decide what works for them. Ideally you’re taking the rads at a point in time when you also can decide what works for you and pass on anything that you cannot live with.
But I think the trend forward is going to be that the folks that pass on imperfect horses are likely to run into things not current found on PPE’s… as they own the perfect horse but are overall less knowledgeable horsemen who can prevent some of these.
Chips
Stress fractures
DJD
OA
Soft tissues strains, tears.
Navicular changes
Laminitis/founder
and my least favorite thing ever… EDM.
There’s no such thing as a perfect horse and I don’t know how to tell people that enough. I believe you should want to know what’s there and what you can live with, but heart and competency of the horse for the job isn’t measured in a PPE.
My best vetted horse ever died, being hit by lightning in a field after 5 years of ownership having competed at Prelim for 4.5 years, with 2 long format 3 days, and ran point to points (with me) after a bowed tendon (I caused) and had a tooth need to be surgically removed, and had a 12" hole in her inner thigh from being impaled by a deer. She recovered fine.
It’s all a crap shoot.
