Many viral videos show dogs howling along with their owners, and while it’s amusing, there’s more to it. Some dogs might actually have a knack for music, trying to match the pitch in their own way.
Psychologist Aniruddh Patel, from Tufts University, led a fascinating study to see if dogs can grasp pitch—the highness or lowness of a sound. The team focused on dogs that enjoyed howling with music. They played songs and recorded how the dogs responded. Later, they played the same songs but changed the pitch slightly to see if the dogs would adjust their howls.
Just like people can change their singing voices to harmonize, scientists wondered if animals have a similar ability. This idea is inspired by wolves, which howl together. Each wolf contributes a unique pitch, creating a powerful and complex sound that strengthens their pack bond. Researchers thought maybe dogs, especially breeds closer to wolves, could show similar behaviors.
The study zeroed in on ancient breeds like Samoyeds and Shiba Inus, which share more genetic similarities with wolves compared to modern breeds. To participate, dogs needed to produce at least 30 howls for reliable results.
The findings were intriguing. For the Samoyeds, all four dogs changed their howls’ pitch when the music changed. Some raised their pitch, while one lowered it. This shift wasn’t random; it showed that these dogs could control their pitch, independent of their mood or excitement.
In contrast, the Shiba Inus didn’t display the same pattern. Their howls stayed mostly unchanged, hinting that not all dogs possess this ability. Genetics could influence how dogs respond to sound, and studying a larger group might offer more insights.
This research may shed light on the origins of music in humans. While many thought musical skills stemmed from language, dogs show they can adjust their pitch without complex language skills. This suggests that musical ability might have evolved long before human speech.
Another intriguing question is why dogs howl with music at all. One theory suggests they perceive music as a call from another animal. This instinctual response resembles how wolves howl as a pack. Observations show that dogs are focused when they howl, indicating they genuinely engage with the sound, rather than just seeking attention.
This study opens new avenues for understanding animal behavior and communication. It shows that some animals might not only hear sounds but respond in sophisticated ways. Research on dogs could reveal more about the broader connections between music and communication, suggesting music may not be exclusive to humans.
So, the next time you hear a dog howl along with a song, pay attention—it might be a glimpse into a simple but evolving musical ability.
For those curious about further details, the findings are published in the journal Current Biology.
