Understanding dog body language and social communication is fundamental to welfare, enabling owners to identify stress, fear, and discomfort before they escalate.
Dogs whose stress signals are consistently missed experience escalating fear that eventually leads to aggression. This cycle begins with subtle calming signals that, when ignored, progress to growling, snapping, and biting. Punishment of growling removes a warning signal and makes dogs more dangerous. The welfare approach recognises all dog behaviour as communication and responds to early stress signals by removing the dog from the situation. Owner education in dog body language is one of the highest-impact welfare interventions available for companion dogs.
