How to read this number

Read alongside breed popularity, veterinary access, and owner awareness, these shape how many events ever reach the FDA. The comparison line marks the cross-breed median death-coded share (4.8%) among breeds with 50 or more reports; values above it suggest higher reporting bias toward severe outcomes, not necessarily higher true mortality.

Source FDA Center for Veterinary Medicine, openFDA adverse event extract (PlainBreed) · July 2026 extract

This histogram uses the same ≥50-report cohort as the highest death-coded share ranking. A higher share means more of this breed's reported events were death-coded, not a mortality rate for living animals.

Terrier - Bull - American Pit among report-volume vs. death-rate peers

Every breed shown has at least 50 filed reports. Volume reflects how often a breed is reported, not how common it is; death rate is the share of a breed's own reports coded as a death outcome.
