At a glanceRead a dog’s body language as a whole and in context. A single tail movement, yawn or ear position cannot reliably explain the dog’s emotional state by itself.WORKING DOG reference library · Added 2026-10-19 · Expert review pendingThis educational guide has not been reviewed by a veterinary professional. Discuss decisions about your dog’s health or diet with your veterinarian.Look beyond one featureThe RSPCA identifies posture, face, mouth, ears and tail as relevant parts of communication. Observe the sequence and the setting: what happened before the dog changed posture, what it did next and whether it could move away. Breed shape, coat and an obstructed camera view can make some features difficult to see.Describe before labellingWrite a neutral observation such as moved behind the handler when the gate opened. That is more useful than claiming the dog was dominant, guilty or deliberately difficult. A photograph captures one moment; a short sequence and knowledge of the situation give an instructor more information to discuss.Respond to uncertaintyIf a dog appears uncomfortable, give space and reduce the demand rather than insisting on a demonstration. Do not approach an unfamiliar dog simply to test your reading of its signals. For handling around children, strangers or livestock, use an appropriate supervision and management plan.Know the limitBody-language education is not a remote diagnosis of pain, fear or aggression. Sudden change, repeated distress or concerning interaction warrants advice from a veterinarian and an appropriately qualified behaviour professional. A public profile should avoid declaring a dog safe or unsafe from a single image.Sources & further readingReferences for this guide.
