Database median

370.0% of 3,648 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.

Greyhound Pet Health Insights

Across the FDA Center for Veterinary Medicine adverse event database, Greyhound accounts for 3,648 submitted reports and currently ranks #55 by report volume within the dog population. Of those reports, 136 involved a death outcome — a 370.0% case-fatality figure calculated directly from the underlying FDA records rather than from external mortality studies. The mean age at time of reporting is 5.4 years, with an average recorded body weight of 30.8 kg (67.9 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 Greyhound are Lack of efficacy (endoparasite) - hookworm (1,322 reports), INEFFECTIVE, HOOKS (874 reports), Digestive tract disorder NOS (528 reports), together capturing a substantial share of the top-reaction traffic seen in this breed's record. On the product side, Ivermectin + Pyrantel As Pamoate Salt appears in 867 reports and is the single most-referenced drug, followed by Moxidectin (370) and Milbemycin Oxime + Praziquantel (310). 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 3,400 reports with a recorded status is dominated by Outcome Unknown (53.4% 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.

Understanding Greyhound Adverse Event Data

Greyhound has a moderate volume of adverse event reports (3,648). Report counts are influenced by breed popularity, owner awareness, and veterinary reporting practices.

The 370.0% 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 Ivermectin + Pyrantel As Pamoate Salt, appearing in 867 reports. This may indicate widespread use of the medication rather than a specific safety concern for Greyhound.
