In a driven hunt with dogs, there are three ways to spur them on.
First, the hunter makes a sharp, guttural cry. To the dogs, this sound means, "Go on! Get 'em!"
Second is firing a shot. As their partners, the hunting dogs trust the hunter. They believe that as soon as the hunter fires, the prey is as good as dead. At that moment, the dogs will give it everything they've got.
Third is when the dogs see their hunter approaching during the hunt. To protect their master, they will turn back and fight with everything they have.
As Hua Xiao'Er ran down the slope, it met Zhao Jun coming up to meet it. Its first instinct was to turn and fight the wild boar. But when it turned, it found it couldn't move a single step.
So it stood its ground, opening its mouth to let out a defiant roar.
