She is very cute! Thanks for the pics, WIRider!
When I was a kid, my dad's Appaloosa suddenly freaked out once - she had never done anything like it before, and never did after either. She was tied at the time, to a stand with a big gas tank on top. (Not ideal... but that's how they'd always done it) She wrenched the stand off of it's foundations and the gas tank came crashing down, thank goodness it didn't break open and nobody got hurt. She continued to fight and thrash terribly until her lead rope broke and then she just stood there, shaking and looking around wildly.
We're pretty sure it was a bee, because after that she HATED the sound of fly spray (we had to soak a rag out of earshot and then rub her down) and anything else that made a buzzing or whirring sound.
