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.?

Imagine being locked in a sterile cage and force-fed toxic chemicals every day. That was Teddy’s life before he was rescued from a Michigan laboratory and adopted. Today, thanks to supporters like you, he loves long naps, cuddles and tennis balls. More than 60,000 dogs just like Teddy are used for research and testing in U.S. laboratories every year. No animal deserves this fate. View Teddy’s story and find out what you can do to help other dogs suffering in labs.

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are better for both animals and humans because they are typically faster, less expensive and more accurate than the outdated animal tests currently in use.

Tested on animals ultimately fail in human trials, according to the National Institutes of Health.

Used in experiments are protected under the Animal Welfare Act or counted in the annual statistics collected by the United States Department of Agriculture.

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.
