As the saying goes, "A cornered dog will jump over a wall", and there is another saying, "A gentle horse will be ridden". But everything has its limits, and if a horse gets too provoked, it may open its big mouth that was originally for eating grass and attack a sheepdog.
This was a real event that happened in Frankfurt, Germany the other day. At that time, a Belgian sheepdog was chasing this seemingly gentle mixed-breed horse. Suddenly, the situation reversed as the horse, which had been driven to a dead end, suddenly became wildly aggressive and began chasing and biting the sheepdog. Faced with such an irrational emergency, the sheepdog, which had been so aggressive at first, could only choose to run away with its tail between its legs.
