Negative planter (hind) angles and how they can affect posture.
If the heels are low, the hair line steep and the dorsal wall 'bull nosed' you probably have the pedal bone sitting at a negative angle, this means the back of the pedal bone is sitting lower than the toe, it's tipping backwards, when it should be slightly elevated at the back, by about 3-5°.
Low planter angles pull on the ligaments & tendons down the back of the leg, pulling it onto 'extension'. It causes tension, you can feel it too if you push your heels down, and this tension transfers to the back, affecting the horse's whole way of going.
Hind legs become 'camped under' because being in 'extension' causes them to stand this way, looking like an elephant on a ball.
This is one reason why you might boot hind feet, to prevent excessive wearing down of the heels.
