Prepared reading examples only. No dog, photo, video or private history is needed. Nothing is saved or sent. Reload resets the tool.
The cards are not a decoder
Each card shows a prepared source-based statement followed by what it does not establish. A wag may be part of communication, but our browser is not a translator of an individual animal. The cards have no happy/angry selector, risk meter, emotion score or behavior prediction. No photograph or description is evaluated. Reload simply resets the reading selection.

Do not hide the qualification
VCA explains that rapid wagging can accompany eagerness or fear and emphasizes the whole posture. It also notes natural tail positions differ across breeds. RSPCA’s examples combine tail information with body posture and other visible features. The limit is part of the meaning: one feature does not determine the emotion or establish a contact decision. A shorter caption must not erase that distinction.

The contact boundary stays independent
No card produces permission to approach, pet or continue an interaction. VCA explicitly warns that a wagging dog may not want engagement. RSPCA describes worried and very unhappy postures as reasons not to approach. The tools do not replace professional advice or the needs of the actual situation. Seek appropriate help for real concerns without waiting for an app response.
