How chronic noise pollution in urban environments affects dog welfare and what owners can do to reduce the impact of sound stressors on their dogs.
Noise pollution is a welfare concern for dogs that is often invisible to their human companions who have already adapted to urban sound environments. The canine auditory system detects frequencies and intensities that humans may barely notice or not perceive at all, making the dog experience of urban noise qualitatively different from the human experience of the same environment. Dogs who appear calm in noisy environments may have adapted behaviorally while still experiencing physiological stress responses. Creating quieter microenvironments within homes, using sound masking effectively, and providing dogs with quiet rest periods are practical welfare measures. For dogs with significant noise anxiety, sound desensitization programs and medication management reduce chronic welfare impacts.
