Collect records from the regular practice, emergency clinics, specialists and any adoption source. The AVMA describes veterinary histories as including preventive care, illnesses, surgery and medication reactions. A short invoice list may not capture that history.
For each concern, record the earliest observed sign, veterinary visits, tests, diagnosis if one exists, treatment and the most recent follow-up. Separate an owner observation from a veterinarian’s finding. If records are missing or an entry is wrong, request a factual correction or explanation from the practice; do not omit the event from an application.
A condition may be relevant before it has a formal name. “The diagnosis was later” therefore may not answer the insurer’s timing question.
