RSPCA’s examples combine features
RSPCA describes relaxed, worried and very unhappy dogs using combinations of body posture, head, ears, eyes, mouth and tail. Its guide does not present a tail in isolation as the whole story. We do not copy its illustrations or claim that our abstract design is a behavioral diagram. The source link is there for the original presentation and context.
VCA’s warning concerns interaction
VCA says a wag can be misinterpreted as friendliness when a dog may want an interaction to end. Its warning is not an instruction to test whether that interpretation is correct by reaching closer or continuing contact. This site supplies no provocation, handling challenge or observation protocol involving strangers, children or other animals. No extra interaction is needed to read these pages.
Unknown does not mean permission
If a crop hides a feature or a description leaves out what happened before, the missing information stays missing. It should not be filled with an optimistic caption. Our frame desk explains that record-design limit without asking the reader to collect more evidence from a dog. No tool result predicts behavior or substitutes for professional help with actual concerns.
