That's just sickening. How can that guy sleep knowing what he's doing to that baby?! I'm sure when he started the filly her bones weren't even close to being ready; I'm waiting until my filly is well past 3 to start her (WB mature slower). Sure, I'm not a fan of gaiting, but NO ONE with a soul could say that's okay. You can almost feel how scared that poor filly is; they probably put the blinders on so you couldn't see the fear in her eyes. There's a special place in he-double hockeysticks for people like him.
I think it's the combination that makes it so heart wrenching - like as if it's not bad enough you're riding a yearling, you're putting unbelievable stress and strain on her legs making her move so unnaturally.
It really makes me question if the rampant unsoundness in big lick TWH is actually due to the stacks they're forced to wear or if it's actually due to starting them SO young. I assume a pretty hefty combination of both - they have 2 year old futurities, and performing a gait so unnatural to them HAS to have serious consequences.
They have videos of older horses showing this horrible wobble they get to their back legs, it's just heart breaking.
