Almost everyone has been disturbed by sudden dog barking late at night. One dog starts barking, and within seconds, the entire street seems awake. While many people see it as random noise, experts say these sounds are actually part of a survival system. Street dogs bark to warn their group, protect territory, respond to unfamiliar movement, and communicate fear or discomfort. At night, their senses become sharper because the surroundings are quieter, making them more alert to sounds humans barely notice. Sometimes, barking also reflects hunger, loneliness, or stress. Understanding this behaviour reveals that these night-time sounds are not meaningless they are part of survival.
