So, a few days ago I was out free lunging Ice in the round pen and we were taking a break. Almost as soon as he stopped he propped his foot up, which although it was the same leg that he likes to rest (his right), I still got kind of paranoid and wanted to make sure he wasn't injured. Nothing was swollen or out of place or anything like that, but the back of his fetlock was pretty warm. I checked his other legs, and his other back fetlock was warm, but not as warm as on that right leg. His front fetlocks weren't warm at all. He moved forward without hesitation, and he wasn't lame. I went out the next day and lunged him again, this time with splint boots on, thinking that maybe he was banging himself, and the same thing happened. They aren't warm when he's at rest, so whats going on here? Keep in mind its not the whole fetlock joint, just the back part where it sticks out.
