See what your farrier has to say. Mine has done wonder with Selena who is a god-awful overreacher. She just powers out so hard that she'll tear herself up. She tore off a show, sliced herself open, tore holes through boots, etc but has done nothing of interest since my farrier worked on her. I'm not a hoof expert and don't pretend to be, so it would be best if you talked to your farrier about it c: Good luck!
Pssh.I didn't pick up the wrong lead
It's called a counter canter...
...A very advanced maneuver.
