I’ve often affectionately joked with my mother-in-law about her ability to talk to her dogs. She responds to their barks with loving understanding. Perhaps now she and dog owners everywhere will also listen for their canine pals to laugh. Scientists have discovered that many animals, including dogs, cows, foxes, seals, and parakeets, all have “vocal play signals”—otherwise known as laughter. Identifying these accompanying sounds helps distinguish an animal’s play behaviors from what might otherwise look like fighting to a human observer.

That animals express laughter and joy gives us a delightful glimmer of what it might look like for other parts of creation to praise God in their own way. As King David looked over his surroundings, it seemed to him “the hills [were] clothed with gladness” and the meadows and valleys were “[shouting] for joy” (Psalm 65:12-13). David recognized that God had cared for and enriched the land, providing both beauty and sustenance.

Even though our physical surroundings don’t “sing” in a literal way, they bear witness to God’s active work in His creation and, in turn, invite us to give praise to Him with our voices. May we—as part of the “whole earth”—be “filled with awe at [His] wonders” and respond to Him with “songs of joy” (v. 8). We can trust that He’ll hear and understand them.
