Wolf howled all day, but as the sun began to go down, he stopped.

Outside, the wolf howled once again, this time in pain.

For the first time in the mountains, we heard wolves howling, but the sound was far away.

He did not enjoy being alone by the river with wolves howling all around.

The rain had stopped, and she could hear wolves howling.

Somewhere, far off among the trees to their right, a wolf howled.

From outside came the sound of wolves howling, and combat.

At that, the wolf threw back its head and howled.

The wolves, after having disappeared for a few days, had again howled in the night.

Up on the hill to the west a wolf howled and was answered by another from the north.
