Reason you check your round yard is safe - YouTube
Sorry its hard to see and looks like just a trip but anyway I was lunging smarty and there was a piece of wire stuff that somehow ended up getting Smartys legs and ripping it, she almost fell regained her balance while keeping on going. I stopped her, checked her over, she was a bit sore for another 5 minutes but was okay after that. So furious...if only aggistment owner would fix the round yard. Trying to find a new aggistment is so difficult but its so dangerous the way this one is.:/ But lesson learnt, I'm glad she didn't get injured because of it.
