What the prompt labels mean

The person didn't share their exact words, so we wrote this from what they described. We haven't tested it, and they didn't use this exact version.

My dog has been limping on a front leg for months and two vets took x-rays and found nothing. Now I've noticed the back right paw is dragging slightly. Here's the full symptom history. What patterns do you see, what could explain them, and what should I ask the vet about next?

Before you start, ask me 1–3 short questions about the details below and wait for my answers. Once I've answered, confirm the plan in one line and run the whole task start to finish.

Goal: Organize my dog's symptom history into a clear timeline and a short list of questions to bring to the vet.

Questions to ask me first:
- How old is your dog, and what breed and weight?
- Which legs or body parts are affected, and since when?
- What tests have vets already done, and what did they say?

Inputs (fill in or confirm):
- Dog's age, breed and weight: [AGE / BREED / WEIGHT]
- Symptoms with dates: [SYMPTOM LOG]
- Vet visits, tests and results so far: [VET NOTES]
- Current medicines: [MEDICINES]

Rules:
- You are not diagnosing my dog; help me describe the pattern clearly so the vet can act on it.
- Point out which symptoms might be connected and what kinds of tests or specialists could look at them, and say what x-rays can and can't show.
- Flag anything that needs an emergency vet now, such as collapse, dragging limbs that get worse, or trouble breathing.
- Keep a running timeline as I add new symptoms in this same thread.

Checkpoint: After the timeline, stop and ask me if anything is missing before you write the vet questions.

If you get stuck: If my notes are too vague to see a pattern, tell me exactly what to watch for and log.

Verify before you finish: Check that every date and symptom in the timeline matches what I told you.

Output: A dated symptom timeline, the possible patterns in plain words, and 3–5 questions for the vet.

Done when: I have a one-page summary to hand my vet and know which signs mean go now.

Outcome

Melissa, a co-founder of the site What Your Vet Missed, describes how Luna, a senior dog, kept limping while two vets with x-rays did not find the cause. Melissa described the symptoms to ChatGPT, which at first covered the basics, like arthritis and soft tissue injury. After Melissa added that Luna's back right paw was dragging slightly, ChatGPT said that changed things significantly: a front leg plus the diagonal rear leg is a classic pattern for a spinal cord lesion, possibly at the neck or upper back, and it noted that standard x-rays cannot show discs or spinal cord compression. The takeaway was that Luna needed an MRI and a neurologist. Melissa kept the same ChatGPT thread open for months as a symptom record. Luna was later diagnosed with an inoperable spinal cord tumor at the neck. In Melissa's words, it was too late for Luna.

Evidence: Described by posterThe person describes what happened in words, without screenshots or video.

Known limitations

PartialThe source says it only partly worked, or had a significant problem a person had to deal with.

What went wrong: ChatGPT spotted the pattern and pointed toward an MRI and a neurologist, but Luna's inoperable spinal cord tumor was found too late to save Luna.
