突

tū

to dash

to move forward quickly; to bulge; to protrude; to break through; to rush out; sudden; Taiwan pr. [tu2]

hole (穴) + dog (犬) = a dog bolting out suddenly

A dog bursting out of a den captures the character perfectly: sudden, forceful, unexpected movement. That image of a dog exploding from a hole is where the sense of 'sudden' and 'dash forward' lives.
