Chartered in 1934, the Animal Defense League is a non-profit organization that is a true no-kill shelter for abandoned, abused, or neglected dogs and cats. Our mission is to enhance the quality of life for these animals by providing needed medical care, including spaying and neutering. While maintaining a healthy and loving facility, ADL consistently works to find the best possible home for each resident animal. Supported by contributions and directed by a volunteer board, the League provides programs and services which strengthen the bond between animals and people. ADL is supported through adoption fees, donations, grants, bequests, and special events to raise needed funds. ADL operates as San Antonio's only true 'no-kill' facility.

ADL operates on the generosity and kindness of friends who believe in our mission. We receive no government or public funding and rely on fundraising, grants and donations to continue our service.
