Many people laugh when their dog howls along with a favorite song. However, new research suggests that some dogs may actually be trying to sing in tune. A study led by Tufts University psychologist Aniruddh Patel found that certain dogs can change the pitch of their howls to match changes in music, as reported by Earth.com.
The research team focused on “ancient” dog breeds, which share more genetic similarities with wolves. Wolves are known for their group howls, where each animal shifts pitch to create a layered, powerful sound. Scientists wondered if some dogs might still have this ability.
To test this, researchers invited dog owners to take part in a citizen science project. Participants played music their dogs liked to howl along with and then played versions of the same songs that were slightly higher or lower in pitch. Owners filmed the howling sessions at home and submitted the videos for analysis.

According to the peer-reviewed study published in Current Biology, four Samoyeds and two Shiba Inus howled enough to be included in the experiment. The results were striking: all four Samoyeds changed their pitch when the music shifted up or down. Three raised their pitch while one lowered it, indicating that the dogs were adjusting their voices in a controlled way, not just reacting randomly.
Importantly, the length of their howls stayed the same. This means the pitch changes weren’t due to excitement; they were intentional.
The Shiba Inus, however, did not show the same pattern. Their howls remained mostly consistent, even when the music changed. This suggests that musical ability may differ by breed, and possibly by genetics.
Researchers say these findings provide clues about the origins of music in humans. People can match pitch naturally, even without training. Yet dogs don’t have complex language, and some can still change their pitch. This supports the idea that musical abilities may have evolved long before human speech.
It may also explain why some dogs howl along with music in the first place. To them, a song might sound like another voice calling out, something worth responding to, just like wolves do in the wild.
This study raises new questions about how animals perceive sound and how musical behavior may have developed across species. It also gives dog lovers another reason to enjoy those heartfelt, sometimes hilarious, living room duets.
So the next time your dog howls along with a song, listen closely. They might be doing more than making noise.
