According to the U.S. Food and Drug Administration's Center for Veterinary Medicine, more than 1,048,915 animal-drug adverse-event reports across 506 breeds had been filed as of the March 2026 data release, drawn from the openFDA Animal & Veterinary Adverse Event database. This tool searches that record for the breed and medication you choose and shows the reactions actually reported for that combination. A report does not prove the product caused the reaction; see our methodology for how the data is sourced and what it can and cannot tell you.

Frequently Asked Questions

What is an animal adverse event report?

An adverse event report is a voluntary submission to the FDA describing a negative reaction a pet experienced after taking a medication, supplement, or food product. These reports do not prove that the product caused the reaction, they indicate an association that the FDA monitors for safety signals.

How should I interpret this risk data?

Use this data as a starting point for informed conversations with your veterinarian. Higher reaction counts may reflect wider product usage (more popular drugs naturally generate more reports), not necessarily greater risk. Always consult your veterinarian before starting, stopping, or changing any medication.

Why are death and euthanasia counts shown?

Death and euthanasia outcomes are reported alongside adverse events. These numbers represent the total deaths/euthanasia in ALL reports involving this breed+drug combination, the adverse event may or may not have been the cause. Context matters: some deaths may be unrelated to the medication.

Can breed-specific risks differ from general drug risks?

Yes. Certain breeds have known genetic sensitivities (e.g., the MDR1 gene mutation in herding breeds can cause severe reactions to ivermectin). Breed-specific data helps identify patterns that may not be visible in aggregate drug safety data.

Where does this data come from?

All data comes from the FDA's openFDA Animal & Veterinary Adverse Events database. PlainBreed is an independent site and is not affiliated with the FDA. Reports span multiple years and include voluntary submissions from veterinarians, pet owners, and manufacturers.
