Is my dog’s bark hoarse?
A hoarse, raspy or suddenly different bark can be nothing — or a sign the voice box is irritated. This tool measures your dog’s voice quality: the harmonics-to-noise ratio (HNR) and vocal roughness that make a bark sound clear versus rough. It’s a gauge, not a diagnosis.
How it works
- 1Record your dog’s normal bark near the mic — everything is analyzed on your device.
- 2The tool measures harmonics-to-noise ratio (HNR) and vocal roughness.
- 3You get a plain-English voice-quality read: Clear, Somewhat rough, or Rough / noisy.
- 4Compare it to your dog’s usual sound over time — and share a report with your vet if it’s changed.
What makes a dog’s bark hoarse?
A change in bark means something has altered how the vocal folds vibrate. Possible causes include laryngitis (inflammation from infection, allergies, or over-barking), respiratory infections such as kennel cough, vocal overuse after a long day of barking, and — more seriously — laryngeal paralysis, which develops gradually in older large-breed dogs and can affect breathing. Significant neck compression or trauma (for example excessive pressure from a collar) can injure the laryngeal region and potentially affect the voice; gastro-oesophageal reflux reaching the larynx may also contribute to irritation, though this link is less well established in dogs.
What “voice quality” actually measures
Harmonics-to-noise ratio (HNR) compares the clean, periodic part of a voice to the noisy part. A clear, healthy bark has strong harmonics and a high HNR; a hoarse or strained voice has proportionally more noise and a lower HNR. Vocal roughness counts irregular, chaotic segments (pitch breaks, subharmonics). Together they’re the acoustic fingerprint of “raspy.” In dogs, higher roughness has been linked to stress and ageing (Marx et al., 2021), which is why tracking it over time is more informative than one reading.
When to see a vet
Treat this tool as a prompt, not an answer. Book a vet visit if the hoarseness persists beyond a few days, keeps returning, or comes with coughing, gagging, reduced appetite, or lethargy. Sudden voice loss with noisy breathing warrants urgent assessment — and if there’s labored breathing, blue-tinged gums, or collapse, treat it as an emergency. Bring a recording — an objective before/after of your dog’s voice quality can genuinely help the exam.
Frequently asked questions
Possible causes include laryngitis, vocal overuse after excessive barking, and respiratory infections like kennel cough. In older large-breed dogs, laryngeal paralysis is a more serious possibility. Persistent or breathing-related hoarseness needs a vet.
Prolonged or excessive barking can irritate the larynx and cause temporary hoarseness or other voice changes. Reducing the barking may help while the irritation settles, but persistent, recurrent, or worsening voice changes warrant veterinary evaluation.
Not necessarily. Aroused, growly, or aggressive barks are naturally rough. This tool measures acoustic roughness — it can’t tell why. Use it to compare against your dog’s normal bark and to decide whether a vet visit is warranted.
The tool estimates HNR from the recording using autocorrelation — the same principle used in clinical voice analysis — entirely in your browser. It’s an estimate from a consumer mic, not lab equipment.
A before/after voice-quality record can be a useful discussion aid. BarkScope can generate a branded acoustic report (PDF) you can hand to your vet.
