The FDA Center for Veterinary Medicine database currently holds 99 adverse event reports referencing Amoxicillin & Clavulanic Acid, including 22 reports in which the animal died — a 2220.0% case-fatality figure among reported events only, not a population-level mortality rate. Active ingredient on file: Amoxicillin & Clavulanic Acid. Reported administration routes include Oral, Unknown. These numbers reflect voluntary submissions from pet owners, veterinarians, and manufacturers and therefore under-represent mild events and over-represent severe ones — a pattern the FDA has documented repeatedly for pharmacovigilance datasets.

The species most frequently named in Amoxicillin & Clavulanic Acid reports are Dog (89 reports), Cat (10 reports), with Dog accounting for the largest share. Within those species, Retriever - Golden (11), Retriever - Labrador (10), Domestic Shorthair (5) appear most often — though breed popularity and ownership density shape these counts as much as any drug-specific sensitivity. This distribution matters because the same active ingredient can behave very differently across body sizes, ages, and species physiology.

The most commonly reported clinical signs associated with Amoxicillin & Clavulanic Acid are Vomiting (17), Other abnormal test result NOS (15), Death by euthanasia (14), Lethargy (see also Central nervous system depression in 'Neurological') (14). Of the 100 reports with a coded outcome, Ongoing is the leading category at 53.0%. Because FDA adverse event data describes correlation rather than causation, these figures are best used to frame informed questions with a veterinarian and to compare reporting patterns across related products — not as a standalone safety verdict on Amoxicillin & Clavulanic Acid.
