A pack of filthy children ran by, screeching at each other.

If a pack runs here now, they have been summoned.

In my neighborhood, there are summer parties where packs of kids run free until after the fireflies are out.

The two packs had run into each other.

Dropping to a steady lope, the pack had run on deep into the forest.

Across a distant valley, the noise echoed back from unseen hills, making it difficult to judge where the pack was running.

As they scramble into trees, a pack of wolves run into the clearing.

A pack of hysterical children ran shrieking down the Promenade.

Still silent, the pack flowed around the pair and ran for the tone.

Somebody was driving the U.S. forces as if a pack of wolves ran right behind them.
