Education, not diagnosis. If your pet seems unwell, contact your veterinarian rather than waiting to read a guide.

About the images

Each guide now has its own AI-created editorial scene and a different detail image inside the article. These imagined everyday situations show observation and preparation. They are not actual patients, stool specimens, product tests or clinical evidence.

Educational diagrams inside the articles explain specific ideas. Read their captions and the sources alongside them; appearance alone does not establish a diagnosis.

HOW PETCHECK USES RESEARCH

Look closely.
Keep the context.

A paper supports only the population, method, and outcome it actually studied. PetCheck does not turn puppy photo scoring into a universal medical claim, or transfer a dog threshold directly to cats. Population, study design, measurement, and limitations remain available in every evidence card.

FROM GENERAL GUIDE TO YOUR OWN RECORD

A small moment.
A clearer record.

Use the same observation language on your own photo. Confirm visible signals, add appetite, energy, vomiting, water, pain, and frequency, then receive one non-diagnostic next step. No account required.
