Dog: adverse event reports for animal drugs

Species

Read this first. FDA says this about the data:

An API dataset query result cannot be used to estimate the risk associated with the product or compare one drug or device product with another. When looking at the results, be aware that there is no certainty that the reported drug or device caused the adverse event. This dataset should not be the sole source of information for clinical decision-making or other assumptions about the safety or effectiveness of a product. The adverse event may have been related to an underlying disease, other drugs used at the same time or other non-drug related sources.

From January 1987 to June 2026, FDA received 1,001,350 adverse event reports about dogs for animal drugs. That is 72.6% of the 1,378,761 reports that FDA received from January 1987 to June 2026.

In the 12 months to June 2026, FDA received 53,340 reports about dogs. The signs that appear in the largest number of the 1,001,350 reports are "Vomiting", "Lethargy" and "Diarrhoea". A report is not proof that a drug caused a sign.

The openFDA records give the value "MSK" for the brand name and for the manufacturer name of each drug. FDA says that MSK means "masked". So the site cannot count a report for a brand.

An API dataset query result cannot be used to estimate the risk associated with the product or compare one drug or device product with another.

Commonly used products may have a higher number of reported adverse events due to the higher total number of animals being given the product.

Where the data come from

The counts come from the openFDA Animal and Veterinary adverse event files, export of 30 Oct 2026. The files have the reports that the FDA Center for Veterinary Medicine received through 26 Jun 2026. The files mask brand and manufacturer names. The site counts a drug by the active ingredients that each record gives, and gives no count to a brand, an application or a company. Ingredient names and the lists of approved products follow the FDA Green Book of 2 Nov 2026.

The site does not publish report text, lot numbers or details of a reporter. FDA's record is the authority. See how the site counts reports, the data sources and the corrections page.

Questions about these reports

What ages are the dogs in the reports?

The figures are shares of the 1,001,350 reports about dogs received from January 1987 to June 2026. 29.2% give an age of 1 to 3 years. 24.5% give an age of 4 to 7 years. 7.6% give no age.

How does the count of the latest 12 months compare with the 12 months before?

FDA received 53,340 reports in the 12 months to June 2026. It received 54,592 reports in the 12 months before. FDA says that a report can take 3 to 6 months to reach the public data. The newest months can get more reports in a later update.

What kinds of report are in the count?

Of the 1,001,350 reports received from January 1987 to June 2026, 69.6% are about a safety issue only. 28.8% are about a lack of expected effectiveness, alone or with a safety issue. 1.5% are about a defect of the product or its package.

Do more reports for dogs show a higher risk for dogs?

No. FDA states this about the data.

An API dataset query result cannot be used to estimate the risk associated with the product or compare one drug or device product with another.

Commonly used products may have a higher number of reported adverse events due to the higher total number of animals being given the product.
