The Animal Defense League was established in 1934 by a group of individuals, “for the prevention of cruelty to animals; to promote kind and humane treatment of animals; and to aid and assist the enforcement of laws enacted for the prevention of animal cruelty.”
In 1961, ADL moved to its present location in the easily accessible northeast part of San Antonio. Its campus encompasses more than 12 acres and includes a two-acre pet park. On the property is an Adoption Center with a small retail store, and a separate 5,000 square-foot Clinic which houses our veterinary hospital that provides onsite spay/neuter surgery, surgery for injured and ill animals, and ongoing medical care for all ADL resident animals.
