Veterinary research highlights dog sensitivity to loud human voices

Research published in the journal Frontiers in Veterinary Science indicates that loud human behavior, such as shouting or sudden movements, can be perceived as a threat by dogs and serve as a significant source of stress. A study involving 386 dog owners suggested that people frequently underestimate how strongly their pets react to noise.

Triggers identified by owners included loud human voices, visitors, moving furniture, and activity in adjacent rooms. While sensitivity is highly individual and influenced by temperament, age, experience, and health, certain breeds—such as the Norwegian Buhund, Irish Soft Coated Wheaten Terrier, and Lagotto Romagnolo—have shown higher levels of noise sensitivity in studies.

According to the University of California, Davis, veterinary experts note that fearful dogs may not always act aggressively or loudly; instead, they often attempt to withdraw. Common signs of anxiety and discomfort include hiding, trembling, panting, lip licking, yawning, lowered ears, body stiffness, restless pacing, whining, or head turning.
