So here I am typing with one hand as my other one hindered by a cast. I got this injury and a few others from missing some cues from Murphy that she may be sore. During the saddling procedure I did notice that she was having trouble softening. We were also aware that she has a tightness in her hind end with picking up her feet which I have been a bit slack lately in relieving it. She has always been calm and easy to ride. NOT last Wednesday. She was easy to catch took the saddle well. Was a little more impulsive after putting the saddle on but this was not unusual. She did the best ever over the barrels too. I had been one rein riding at the walk practicing one rein stops and rein positions. We were just walking her head was low and ears forward, she turned to the right at the corner took about two steps and just exploded into something between a buck and deer leap. Even after I was off she kept going until the next corner. It was like she had a sudden pinched nerve. So even though I knew what to look for and saw some indicators that I had seen before and all was well before, it wasn't good enough to just accept it as good enough just because it had been normal for her didn't mean it wasn't still bad and by not being on top of it I got myself in an unsafe situation. It may be the smallest of signs and when you have a forgiving horse like Murphy it is easy to get complacent and bad things can happen. I hope this helps someone else to take more notice of the little signs and keep safe out there.
