I don’t know if he had a slipped tendon or something else? Mine with the slipped tendon were very painful. Straightening their leg, which I attempted as part of physical therapy, was agonizing for them. Forrest seems far more comfortable with his leg than they were...Do you think Forrest has/had a slipped tendon? I always wondered what is wrong with his leg. It does seem deformed from the hock on down - if I am saying that correctly - no idea - just using horse analogy (a bit lazy, I'm sorry, I could look it up online, I suppose).
He did not seem to suffer or did not show it, though. But the leg was bent out from the next joint up and I think the toes curled in the opposite direction to compensate. Leg out, toes in.
