Plain-English summary
A study found that dogs with tracheal collapse often make a honking sound, while those with laryngeal paralysis produce a specific type of noisy breathing called stridor. Researchers recorded and analyzed the sounds from affected dogs and compared them to healthy dogs. The findings suggest that these distinct sounds could help veterinarians diagnose these conditions more easily. If your dog is making unusual noises while breathing, it's important to consult your vet for an evaluation.

Abstract
The aims of this study were to investigate whether upper airway sounds of dogs with laryngeal paralysis and tracheal collapse have distinct sound characteristics, compared with unaffected dogs. The sounds of 5 dogs with laryngeal paralysis and 5 dogs with tracheal collapse were recorded. Honking sound appeared as predominant clinical signs in dogs with tracheal collapse. Laryngeal stridors appeared as predominant clinical signs in dogs with experimentally produced laryngeal paralysis by resection of laryngeal nerve, in which two types of stridor, I and II, were recorded. All these sounds were analyzed using sound spectrogam analysis. There were significant differences in duration (sec), intensity (dB), pitch (Hz), first formant (Hz), second formant (Hz), third formant (Hz), fourth formant (Hz) of sounds between the normal bark and two types of stridor or honking sound, indicating that the sound analysis might be a useful diagnostic modality for dogs with tracheal collapse and laryngeal paralysis.
