Dogs communicate through a rich repertoire of body language, vocalizations, and calming signals that are often misread or ignored by owners.
Understanding dog communication is a fundamental welfare issue. Dogs that cannot effectively signal their emotional state to humans — or whose signals are consistently ignored — are more likely to experience chronic stress, to bite without warning, and to be relinquished or euthanized. When owners suppress growling as a warning signal through punishment, dogs may skip earlier warning signals and escalate directly to biting. A welfare-centered approach to dog ownership involves learning to read the full spectrum of communication signals, responding appropriately to signs of stress or discomfort, and creating environments in which dogs feel safe enough to express themselves honestly. This benefits both dogs and the humans they live with.
