The Sato Project is an animal rescue and protection organization founded in 2011 by British-born Christina Beckles. It works to rescue abused and abandoned dogs in Puerto Rico, educating the public, and advocating for abused and abandoned dogs. "Sato" is the Spanish word used in Puerto Rico and Cuba for referring to stray dogs or cats. Many of the project's missions have involved airlifting dogs before and after natural disasters, including Hurricane Maria in 2017 and the earthquakes that struck Puerto Rico in 2019 and 2020. "Spayathon" is a spaying and neutering program, attended by Sato Project and other animal rights organizations in Puerto Rico, which has had an impact on the stray dog population.
