Some of NYC’s Animal Shelters

The Sato Project — One of the island’s best-known rescue groups, The Sato Project focuses on large-scale rescues, rehabilitation, spay/neuter, and transporting dogs to partner adopters in the mainland U.S. They’ve saved thousands of dogs and regularly run flight missions moving animals from crisis to safety.
