我把这种称为阶梯假象，实际上，当阶梯假象突然结束了，他就会停住了，这叫做步态冻结。

I call this the staircase illusion, and actually when the staircase illusion abruptly ended, he froze, and this is called freezing of gait.

能够在实际的运动中来看犬种的结构和当狗在小跑步时来看骨骼的协调和步态并且连续的纪录下来是非常好的。

It was fascinating to see the canine structure in actual motion and to see the coordinated movement of the bones as a dog trotted on a treadmill and his gait was recorded continuously.
