690.0% of 1,326 reports involved a death outcome. Read alongside breed popularity, veterinary access, and owner awareness — these shape how many events ever reach the FDA. The 12% comparison line is the rough cross-breed median in the FDA CVM database; values above suggest higher reporting bias toward severe outcomes, not necessarily higher true mortality.

Across the FDA Center for Veterinary Medicine adverse event database, American Pit Bull Terrier accounts for 1,326 submitted reports and currently ranks #92 by report volume within the dog population. Of those reports, 91 involved a death outcome — a 690.0% case-fatality figure calculated directly from the underlying FDA records rather than from external mortality studies. The mean age at time of reporting is 5.5 years, with an average recorded body weight of 26.6 kg (58.7 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.
The most frequently reported clinical signs for American Pit Bull Terrier are Vomiting (318 reports), Lethargy (see also Central nervous system depression in 'Neurological') (171 reports), Emesis (144 reports), together capturing a substantial share of the top-reaction traffic seen in this breed's record. On the product side, Trilostane appears in 372 reports and is the single most-referenced drug, followed by Milbemycin Oxime + Spinosad (341) and Spinosad (79). 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 1,327 reports with a recorded status is dominated by Outcome Unknown (41.9% of coded outcomes). Annual submission volume ranges from 2,010 to 2,025 reports across the 16 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.
American Pit Bull Terrier has a moderate volume of adverse event reports (1,326). Report counts are influenced by breed popularity, owner awareness, and veterinary reporting practices.
The 690.0% death rate is above average, though this statistic should be interpreted cautiously. Death reports may be overrepresented because serious outcomes are more likely to be reported than mild reactions.
The most frequently referenced drug in adverse reports is Trilostane, appearing in 372 reports. This may indicate widespread use of the medication rather than a specific safety concern for American Pit Bull Terrier.

The reporting process and database limitations
Adverse event data sourced from the FDA Center for Veterinary Medicine via the openFDA Animal & Veterinary Adverse Events API. Reports are voluntarily submitted by pet owners, veterinarians, and product manufacturers.
American Pit Bull Terrier ranks #92 by total report volume. Death rate (690.0%) reflects the proportion of reports involving death and should not be interpreted as a breed-specific mortality rate. Reporting biases, breed popularity, and veterinary access all influence report counts.
