Does Music Actually Calm Dogs? What Twenty Years of Research Really Says

You have probably been told to put on classical music for a nervous dog. It is the single most repeated piece of advice in this space, it is usually attributed to "studies," and the studies are almost never named.

They exist. There are about twenty years of them. They are more interesting than the advice they turned into, and the best one found that classical music was not the winner.

Where the classical claim comes from

Two real studies, and they both hold up.

Deborah Wells, Lesley Graham and Peter Hepper at Queen's University Belfast published the first one in Animal Welfare in 2002. They exposed 50 shelter dogs to classical music, heavy metal, pop, recorded human conversation and silence. Classical produced more resting and less barking. Heavy metal produced more barking and more agitation. Pop and conversation did roughly nothing.

Ten years later Lori Kogan, Regina Schoenfeld-Tacher and Allen Simon at Colorado State University ran a larger version with 117 kenneled dogs, published in the Journal of Veterinary Behavior in 2012. Same direction: dogs slept more and vocalized less with classical, and heavy metal increased body shaking, which is a recognized stress signal rather than a dog having a great time.

So the folklore is not wrong. It is just incomplete, and it stopped reading in 2012.

The study that complicated it

In 2017 Amy Bowman, Neil Evans and colleagues at the University of Glasgow, working with the Scottish SPCA, published the study that should have replaced the advice. It ran in Physiology and Behavior and it is the most rigorous of the bunch, because it did not rely on someone watching dogs and writing down impressions. It measured heart rate variability, a physiological stress marker, alongside behavior, across 38 kenneled dogs.

They tested five genres: classical, soft rock, Motown, reggae and pop.

Two findings, and the second matters more than the first.

Every genre beat silence, and soft rock and reggae came out ahead of classical. That alone should end the "put on Mozart" reflex.

Playing one genre on repeat stopped working. Dogs habituated to a single type of music within about a day. Rotating genres sustained the calming effect for longer than any single genre could, including the winners.

The researchers were also careful about something the popular write-ups dropped: individual dogs responded differently, and the team explicitly cautioned that dogs may not have a "taste" in music the way a person does. What is being measured is an effect on arousal, not a preference.

Cats are a genuinely different problem

Cats hear higher, communicate differently, and mostly ignore music written for human ears.

Charles Snowdon and Megan Savage at the University of Wisconsin, working with the cellist David Teie, tested this properly in Applied Animal Behaviour Science in

  1. They built music around frequencies and tempos drawn from cat

vocalizations, purring and the rhythm of kitten suckling, then played 47 cats both that and ordinary human classical music. The cats showed a significant preference for the cat-specific music: orienting toward the speaker faster, rubbing on it, purring.

Here is the part that gets left out of every article about this study. In a 2016 commentary on the same work, Cinzia Chiandetti noted that humans also liked the cat music. If people enjoy it too, the effect may come from general musical principles like consonance and tempo rather than anything exclusively feline. That does not invalidate the finding. It does mean "species-specific music" is a weaker claim than it is usually sold as.

The finding nobody selling you an app will mention

A 2025 study in the Journal of Veterinary Behavior compared music specifically designed for dogs against ordinary relaxation music and found no added benefit from the purpose-built version.

That is worth sitting with, given how much audio is now marketed as scientifically engineered for your dog. The evidence that music helps a stressed animal is genuinely decent. The evidence that it has to be special music is not.

So what do you actually put on

Based on what the research supports, rather than what sells:

literature and the one most people skip. Same playlist every day stops working within about a day.

classical is fine and everything beat silence.

markers in kenneled dogs. It is not a treatment. Genuine separation anxiety needs a vet or a behaviorist, and audio is at best a small supporting piece.

Spotify has reported that roughly 71 percent of pet owners already play music for their pets, so most of us are doing some version of this anyway. Doing it on rotation is free and appears to work better.

Where a song about your pet fits, honestly

It does not fit here, and I would rather say so than pretend otherwise.

Everything above is about ambient audio changing an animal's arousal level. A song about your dog is a completely different object. It has vocals, dynamics and a structure designed to hold a human's attention, which is close to the opposite of what calming background music is supposed to do.

And to be clear about a claim we will not make: there is good research showing cats respond to their own name, notably a 2019 study by Atsuko Saito and colleagues in Scientific Reports, and there is solid work out of Eötvös Loránd University on how dog brains process words and tone. Nobody has tested whether an animal recognizes their name sung inside a piece of music. Different prosody, different pacing, different everything. Anyone telling you your dog knows the song is about them is guessing, and so would we be.

The song is for you. That is the entire point of it, and it is enough.

Put on rotating soft rock for the dog. Make the song for yourself.
