History of World Day for Animals in Laboratories

Established in 1979 by the National Anti-Vivisection Society (NAVS), World Day for Animals in Laboratories was created to spotlight the ethical concerns surrounding animal testing. The date, April 24, was chosen to honor the birthday of Lord Hugh Dowding, a prominent British military officer and advocate for animal welfare, who served as NAVS president after World War II. ​

Over the years, this observance has gained international recognition, prompting demonstrations, educational campaigns, and policy discussions aimed at reducing and ultimately eliminating the use of animals in laboratory research. It has also led to the establishment of World Week for Animals in Laboratories, a week-long series of events surrounding April 24. ​

Why is World Day for Animals in Laboratories important?

Each year, millions of animals—including mice, dogs, monkeys, and rabbits—are used in laboratory experiments worldwide. These animals often endure procedures that cause pain, distress, or death, raising significant ethical and scientific concerns. Critics argue that species differences can render animal testing unreliable for predicting human responses, and that such practices may hinder medical progress. ​

World Day for Animals in Laboratories serves as a catalyst for change, encouraging the development and adoption of alternative research methods that do not involve animals. It also fosters public awareness about the limitations of animal testing and promotes a shift toward more ethical and effective scientific practices.​
