Chronic exposure to noise pollution including traffic, construction, and fireworks causes long-term welfare harm in dogs through sustained stress responses.
Chronic noise stress is an underappreciated welfare harm - unlike acute fear events, the cumulative physiological and psychological cost of sustained noise exposure is invisible but real. Urban dogs living near major roads may experience chronic low-level stress that impairs immune function, sleep quality, and quality of life. Soundproofing rest areas, providing quiet retreats, and advocating for reduced noise pollution in residential areas are welfare priorities.
