Speed has more than one setting
VCA describes rapid movement in different emotional situations and slower wagging in tentative interactions. Those examples are not a calibration table for a website. The article does not give this tool a validated threshold for deciding an individual dog’s mood. We deliberately include no timer, frequency entry or slow-to-fast emotion slider. The useful question is what the source actually claims.
Neutral depends on the animal
VCA notes that the natural tail position varies by breed and describes several examples of different tail shapes. A high or low label therefore needs a reference rather than an assumed straight-tail silhouette. This guide performs no breed classification, image measurement or tail-angle calculation. It also does not infer a dog’s emotional state from its shape or the absence of a visible wag.
Combining shortcuts does not create a safety test
Adding speed to height still does not authorize this website to decide whether contact is safe. VCA stresses interpretation with the rest of the body, and RSPCA’s examples are whole-posture descriptions. Our wording cards retain that broader context without making a checklist whose completion clears the interaction. A reader with a real concern should seek suitable help.
