DogHushLeaving calm music or a radio on is worth trying: shelter studies found dogs rest more and bark less with classical music, and steady sound masks the hallway and street noises that trigger alert barking. The calming effect is modest and fades within days if you play the same thing, and it does not treat separation anxiety.
What do the studies show?
- Classical music, calmer dogs. In a shelter study of 50 dogs, classical music meant more time resting and quiet; heavy metal meant more barking; pop and human conversation made no difference (Wells, 2002).
- It wears off. A later kennel study found classical music reduced barking and improved heart-rate measures, but the effect was gone by day seven, with signs of habituation as early as day two (Bowman, 2015).
- Variety helps. Across five genres, soft rock and reggae produced the most relaxed heart-rate patterns, and the authors suggest rotating genres (Bowman, 2017).
- Talk is mixed. Audiobooks increased resting in kennelled dogs in one study (Brayley & Montrose, 2016), but in pet dogs during a short separation an audiobook only made them stare at the speaker (Kinnaird & Wells, 2022).
All of this is about calm. There is no controlled study of white noise for pet dogs left at home, so treat white noise purely as sound masking.
So what should I put on?
| Sound | Use it for | Watch out for |
|---|---|---|
| Classical, soft rock or reggae playlist | General calm | Rotate every few days |
| Talk radio | Masking, and a lived-in house | Evidence of calming is mixed |
| White noise or a fan | Masking footsteps, doors, distant dogs | No calming evidence |
| TV | Masking | Doorbells, knocks and barking dogs in adverts and shows |
Where should the speaker go, and how loud?
Between the dog and the trigger, not next to his bed: by the front door for hallway noise, by the street window for traffic and passers-by. Keep it at conversation level. Louder isn’t calmer, and his hearing is more sensitive than yours.
What won’t it fix?
Separation anxiety. A dog who panics when left isn’t short of background noise; the ASPCA and Merck describe gradual, supervised absences as the treatment, sometimes with medication from a vet. It also won’t teach anything. Masking makes barking less likely; a trained cue is what stops a bark that has started, which is the job DogHush does when you’re out.

This guide is general information about dog behaviour, not veterinary advice. A sudden change in barking, or barking with signs of distress, is a reason to see a vet.
