At first Timothy(tiger cub) appeared to be quite afraid of the puppy, and darted with a spring if it came too near. He would make absurd dashes at it with his large forepaws, and then retreat to a ridiculously safe distance.
What does `spring' mean here?
Also, please rephrase the highlighted sentence.
He would rush at it making ridiculous attacking gestures with his paws, then run away.
