Also in the same respects, if you have a wonderful horse whom is a total packer, is great for your riding style, is a babysitter or husband horse, but won't pass the FLEX... then what? Do you drop horse all together?
I would assume that most horses, in the grand scheme of things, struggle passing the PPE. Especially if we are talking about a horse that is a wee bit older, is used and ridden, and has changed owners a few times.
So how does everyone feel about this? Did you PPE your horse? Is it an absolute deal breaker when a horse doesn't "pass".
