>>1987175Think you're looking too much for one single answer on the 2nd question.
Simple answer is yes. I'd imagine a trainer who deals with a certain horse all the time would have alot more respect from said horse even if he/she is riding another. Complex answer is depends on a ton of factors that the horse is considering.
I know if my teacher went into a herd pen to put a particular horse away, the other horses would keep a good distance away from her and the horse. If a new student was doing it, the herd will more likely mess with the horse being put away, especially if its low on the pecking order.
For the first part, ya, kind of. Seems to be a cooldown period from a horse that becomes gelding from a long-time stallion. Otherwise pre-pub geldings tend to be as docile as possible.
