Was longing Tesla when I realized that something was amiss - the horses next to the arena were flipping out, leaping and bucking and snorting (and in turn spooking Tess, who decided must-go-faster was the answer) it took a bit of time for me to get Tesla relaxed and walking calmly on the line, despite the antics happening around her - and when I finally did, I walked her over to investigate - and realized a horse was loose!
This is particularly scary on this bit of property as the entire facility is not fenced. It is next to a road that can get busy on the weekends. I hollered to the trainer if help was needed (of course didn't have my phone - note to self ALWAYS put phone in pocket!) although I'm not sure what I could've done as there was no empty stall/paddock to put Tesla in - and I absolutely did not want to take her over and make the situation any worse!
The trainer managed to herd the loose mare back towards her paddock (which had the door open) and thankfully the little old lady galloped right in, and crisis averted.
Glad it ended safely for all involved!!
Do you have a scary loose horse story?
