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 (about 4.8%) among breeds with 50 or more reports; values above it suggest higher reporting bias toward severe outcomes, not necessarily higher true mortality.
