Observation and interpretation
Observation means what you actually saw or heard. Interpretation is the explanation you attach to it. Dog licked a hand is an observation; dog apologized is an interpretation. This original distinction keeps a note honest. It does not claim the website can identify an emotion from a sequence of events.
Reinforcement and attention
Dogs Trust explains reward-based learning as behavior becoming more likely when followed by something the dog wants. Attention may be rewarding. The term does not mean every lick has the same function or that a person should ignore a health concern. Applying a plan to an individual dog needs appropriate professional guidance.
Greeting and self-licking
People-directed greetings and licking the dog's own body are different observations. Dogs Trust discusses several reasons for both and advises veterinary help for concerns. Neither label is a diagnosis or proof that behavior is harmless. Keep the body area, setting and change separate from any explanation.
Unknown and boundary
Unknown means not established. Boundary means a preference or limit for interaction, such as wanting a different routine greeting. Neither is a judgment about the dog's character. Our tools produce question notes, not a safety classification, training prescription or conclusion about affection.
