Together, we can reduce⁠—and eventually eliminate⁠—harmful animal testing and research.

Each year, more than 25 million dogs, cats, monkeys, horses, guinea pigs and other animals are forced to endure painful experiments in the United States. Animals are deliberately sickened with toxic chemicals or infected with diseases, live in barren cages and are then killed when the experiment ends. Humans and animals are very different, so animal experiments often produce inaccurate or unusable results.

LIFE IN A LAB

Harvey never basked in the sun, chased after a ball or knew what it was like to be loved. As part of an experiment, his chest was surgically opened and flooded with substances to test for toxic effects. He suffered alone in a wire cage in a sterile laboratory—and then he was killed. More than 60,000 dogs just like Harvey suffer in U.S. laboratories every year. It breaks our hearts that it’s too late for Harvey, but we are on the forefront of a global movement to replace animals in harmful experiments with high-tech, non-animal alternatives.

Modern alternatives

The world is rapidly moving toward a future where laboratories use human cells and tissues, 3D printing, robots, computer modelling and other sophisticated methods to carry out experiments. These technologies are better for both animals and humans because they are typically faster, less expensive and more accurate than the outdated animal tests currently in use.

Millions of animals are used in harmful experiments each year at universities, hospitals, government facilities and companies around the country. Help us work toward the day when animals no longer suffer in laboratories.
