The mean age at time of reporting is 5.7 years, with an average recorded body weight of 30.2 kg (66.6 lbs). These figures reflect the voluntary reporting pool only and should be read alongside breed popularity, veterinary access, and owner awareness — all of which shape how many events ever reach the FDA.

Counts like these surface which therapeutic classes dominate the reporting stream — useful context when comparing reactions across breeds of the same dog species.
Outcome coding on the 122 reports with a recorded status is dominated by Ongoing (45.1% of coded outcomes). Annual submission volume ranges from 2,017 to 2,025 reports across the 6 years on file, indicating the reporting trend is shaped as much by awareness cycles as by underlying clinical events. Because FDA adverse event reports describe correlation rather than causation, these numbers are most useful as a signal of where to ask further questions with a veterinarian — not as a standalone risk score for any individual dog.
