The ASPCA’s deep-rooted commitment to horses dates back to its founding in 1866, inspired by Henry Bergh’s witnessing of horse cruelty. Bergh pioneered innovations such as the world’s first horse ambulance and a canvas sling for rescuing trapped horses, while the organization established watering stations and advocated for humane treatment of working horses in New York City. Throughout history, the ASPCA responded to crises like the 1872 Great Epizootic equine influenza outbreak and adapted to changing urban technologies, continuously shaping policies to protect horses, including efforts to regulate carriage horse industries and combat horse slaughter.

In modern times, the ASPCA continues to champion equine welfare through initiatives like the ASPCA Maclay National Championship, the Right Horse Initiative promoting equine adoption, and the Equine Transition and Adoption Center in Oklahoma. These programs have helped thousands of horses find homes and receive care, reflecting the ASPCA’s ongoing legacy of compassion and innovation in equine protection. The organization also advocates for humane management of wild horses and legislative efforts to end horse slaughter, underscoring its enduring role in advancing the welfare of horses nationwide.
