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 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
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.
You are not buying the costume for the dog. The dog does not want the costume. The dog has never once wanted the costume.
You are buying it because for about nine seconds your dog is going to look like a tiny confused pirate, and you want that on your phone forever.
The numbers back this up more than you would expect. The National Retail Federation's Halloween survey, run 2 to 9 September 2025 across 8,045 US consumers through Prosper Insights and Analytics, found that 23 percent of people celebrating Halloween planned to dress up a pet, and that pet costume spending reached 860 million dollars in 2025, up from 700 million the year before. A MetLife Pet Insurance survey went further and found 27 percent of pet owners bought a costume specifically to post it on social media.
So a quarter of us are, by our own admission, doing this for the content.
Fine. Let's do the content properly.
Shoot the reaction, not the costume
The costume is the least interesting thing in the video. Everyone has seen a hot dog costume. Nobody has seen your dog's specific face when he realizes he is wearing it.
Put the camera down at their eye level before you put the costume on. Film the walk, the first shake, the moment they freeze and stare at you like you have betrayed the family. That is the video. The costume is just what caused it.
The five second rule that actually matters
If your pet is genuinely miserable, you have about five seconds of usable footage and then you have a pet who hates October.
Signs to stop: tucked tail, pinned ears, whale eye, freezing in place, trying to back out of it. A dog standing still because he is confused is funny. A dog standing still because he is shut down is not, and it reads on camera even if you do not notice it in the moment. Get the shot, take it off, hand over something excellent.
Cats: you know already. You have about one and a half seconds.
Everyone uses the same four sounds
Here is where these videos actually fall apart.
Scroll pet Halloween content and you will hear the same handful of trending audio clips over and over, because that is what the app suggests and because a trending sound is supposed to help reach. The problem is that a borrowed sound is doing the emotional work, and it is doing it identically for ten thousand other videos that week. Your dog becomes a stock image with someone else's joke playing over him.
Most people arrive here for a reason. They love their pet more than they know how to write and record a song about. Here are the occasions we've pre-built into the app:
Dog birthdays
Turn on Birthday Mode and give us their age. You get a song that actually names the number, which beats singing the regular birthday song at an animal who has no idea what's happening.
Shelter dogs with a guessed birthday: say so. "Vet thinks around April" is funnier and more honest than a made-up date, and the lyrics will use it.
Pet adoption days
The adoption anniversary is the one that tends to be...distinct. At least mine were.
Give us the arc: where they came from, how bad the first week was, what they're like now. A dog who spent three days under the kitchen table and now lovingly charges every visitor is a complete narrative, and the song will reflect it.
Memorials
Memorial Mode changes the tone of the whole song.
Give us the specifics rather than the sentiment: the way she knocked things off the shelf, the exact spot he slept, the sound she made at the door. Specifics are what make a tribute sound like them instead of like a greeting card. I realize this can be bittersweet, but for my pets who have moved on, the songs I've made for them with this service are so close to my heart. Something I wouldn't trade for the world. This is why I decided to incorporate this mode into TailwagTune.
