Tail Talk: reading the half of the conversation your dog is already having

This is a submission for Weekend Challenge: Dog Days Edition What I Built Tail Talk reads a dog's body language from a photo. You upload a picture. Gemini walks the whole dog; ears, eyes, mouth, tail, posture, weight distribution, hackles ; and reports what each part is saying, checks every rung of the canine ladder of aggression, and tells you what to do and what to avoid right now. The thing that pushed me to build it: dogs warn us for a very long time before they growl. A lip lick. A yawn that isn't about being tired. A head turned away. A crescent of white in the eye. These are the quiet rungs of a ladder, and it ends in a bite only because everyone in the room missed the first eight steps. Most bite incidents aren't a dog "snapping without warning"; they're a dog that asked politely, repeatedly, in a language nobody around it spoke. Tail Talk is a phrasebook for that language. My goal was deliberately narrow: not a breed identifier, not a cuteness scorer. Those exist. I wanted an evidence-first behavioural report; one that shows its working, and admits what it cannot see.

Here's the read it gave on the Jack Russell sample — note that it caught the breed confounder on its own: ▎ Happy, energetic, and engaged · Safe to approach ▎ Arousal 60 · Comfort 85 ▎ ▎ Tail: tail held high and upright above the backline — confident, high interest or excitement, typical for this breed ▎ ▎ Caveat: "Jack Russell and terrier breeds naturally carry their tails high and erect, which represents normal breed posture rather ▎ than high tension."
