Canine vocalizations do include a distinct play signal that ethologists classify as laughter, but it looks and sounds nothing like the internet's favorite videos. In the early 2000s, animal behavior researcher Patricia Simonet recorded shelter dogs engaging in social play. She identified a specific breathy, unvoiced sound that differed measurably from standard thermoregulatory panting.

While normal panting maintains a flat acoustic profile across a narrow frequency band, Simonet found that play panting bursts across a broad frequency spectrum up to 4,000 Hz. When Simonet played these recordings back through shelter speakers, stressed dogs settled, heart rates slowed, and barking decreased dramatically. Behavior specialists have corroborated these findings, documenting how play-pant exhalations serve as an invitation to romp rather than a display of humor.

Crucially, true canine laughter is entirely voiceless. Dogs lack the vocal fold articulation, pharyngeal structure, and supralaryngeal tract modulation needed to produce segmented, percussive vocalizations like "haha" or "hehe." When a video features a golden retriever emitting pitched, rhythmic chuckles, the sound track has invariably been added in post-production.
