Together, we can reduce⁠—and eventually end⁠—harmful animal experiments.

Each year, it is estimated that more than 25 million dogs, cats, monkeys, mice, rats 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 typically killed when the experiment ends. Humans and animals are very different, so outdated animal experiments often produce results that cannot accurately predict human responses.

RESCUED FROM A LAB

Imagine being locked in a barren cage and force-fed pesticides every day. That was Teddy’s life before he was rescued from a Michigan lab and adopted. Today, thanks to supporters like you, he loves long naps, cuddles and tennis balls. More than 50,000 dogs just like Teddy are used in experiments each year in U.S. laboratories and many are killed at the end. No animal deserves this fate. View Teddy’s story and find out what you can do to help other dogs suffering in labs.

Non-animal methods

The world is moving toward a future where scientists 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are better for both animals and humans because they are typically faster, less expensive and more accurate than the outdated animal tests currently in use. With your help, we can make sure this change happens more quickly.

Are still waiting to be moved out of labs and into sanctuaries even though invasive experiments on chimpanzees in the United States ended in 2015.
