If a dog was indeed agressive (i.e. Prone to unprovoked attacks), I'm sure this would not of been an isolated situation. It sounds as though it was bad timing for the Op.
Dog, cat, person, horse, snow falling off the roof, truck driving by, ATV's, etc. A horse will encounter many things in their life. Some may startle them, some that 'should' - won't and other things that shouldn't - do.
