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.

Contacting a veterinarianHow to report to FDAFrom February 1987 to December 2023, FDA received 753 reports that give the breed Old English Sheepdog. That is under 0.1% of the reports about dogs. In the 12 months to June 2026, FDA received no reports for this breed.
The count has only the reports that give this one breed. Reports about crossbred animals are in the count for the species. The signs that appear in the largest number of the 753 reports are "Vomiting", "Diarrhoea" and "Emesis". A report is not proof that a drug caused a sign.
By number of reports in all years, this breed is number 99 of 167 breeds of dogs with a page. Fewer than 20 reports gave this breed in the 12 months before June 2026, so this page gives no change. The sign "Vomiting" is in 24.3% of the reports that give this breed, and in 19.6% of the reports about dogs.
Search engines list a breed page with 1,500 reports or more in all years. The page also needs 30 reports or more in the 12 months to June 2026. This page is under one of these numbers. The site keeps the page and keeps it out of search engines.

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 puts the FDA breed label in the usual order of the words.
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 animals in the reports?
The figures are shares of the 753 reports about this breed received from February 1987 to December 2023. 30.1% give an age of 8 to 11 years. 21.9% give an age of 4 to 7 years. 2.1% give no age.
- How does the count of the latest 12 months compare with the 12 months before?
FDA received no reports in the 12 months to June 2026. It received no 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.
- Why are crossbred animals not in the count?
The site counts a report for a breed only when the report gives one breed. A report for a crossbred animal can give more than one breed, and a count for each breed would count the report more than once. The reports about crossbred animals are in the count for dogs.
- Do the reports show that this breed reacts more to a drug?
No. The reports do not give the number of animals of the breed. FDA states this about the data.
