I am not saying not to react, correct the horse or defend oneself from this behavior. All I am saying is that this does not sound like a "disrespect" or "training" issue. I have seen perfectly safe, sane, and wonderful horses turn into dragons over being in pain. This kind of behavior does not happen overnight with no previous signs with a horse who is being well maintained. They do not wake up one morning and think "I am going to be aggressive today." From at least the ones I have dealt with and known for the last 20 years, they are all fairly consistent in their behaviors. The ones that "know better" (I say lightly) usually don't jump immediately to all out aggression when trying to test the handler. Extreme attitude changes with no prior warming are almost always linked to a health issue. Which is why a once-over from a vet would be a good thing.
