i recently found out the funniest thing about big horses recently which is that for centuries humans have sworn that the feathering on big horse’s legs has been bred in there for a reason, and the reason given is usually something to do with how it helps keep the joints warm and safe when the big horse is doing hauling work in fields.
the thing is: it doesn’t appreciably do that, because the feathers wick up water and mud, which cancels out any insulation advantage they might hypothetically confer, and also it wasn’t even put there on purpose.
the Leg Get More Hair gene is just linked to the Bones Get More Big gene. when you breed any lineage of horses to have bigger bones–not just taller, but chunkier–the leg hair just happens anyway. so every single breed of draft horse has feathered legs, and even carriage horses like friesians get feathers once they hit a certain threshold of lorge.
when you supersize your horse, mother nature throws in a free pair of booties. how cool is that?
