Frequently asked questions

What should I log when my dog seems unwell?

Note the date, the symptom you observe, how severe it seems, appetite and energy changes, and anything unusual before it started. Photos or short videos help too.

How is a symptom log different from a diagnosis?

The log records what you observe over time. Diagnosis and treatment stay with your veterinarian — the log gives them the timeline they need to work faster.

Can I share the log with my vet?

Yes. In PetMerge the entries live in your dog's record and can be exported as a PDF or shared as a read-only link for the appointment.
