Well, it all depends on the horse. It's hard to really tell if something little is off if you haven't seen their movement a lot. For example, the grey mare I posted. You can tell she is off on her hind end just for the fact she looked uneasy and short strided...It wasn't overly noticeable, but it was there. The reason I could tell it was her right is because I've watched that video over and over (lol!) and I saw her in person. Just depends on the situation and horse.
