Welcome to The Animal Defense League website

The Animal Defense League is the largest true 'no-kill' non-profit animal shelter in the Southwest. For over 75 years of continuous operation, thousands of dogs and cats have been taken in by the ADL each year, given needed medical services, then provided food, shelter, and compassion while we search for permanent and loving homes for all of them.

Please use this website to learn about the wonderful dogs and cats who might be the perfect pet companions you’ve been looking for. Visit all of our adorable ADL residents online in our Pet Personals section, then come out to visit them at our at 12-plus acre campus in near-northeast San Antonio.

This website also contains valuable information including Lost and Found tips for dogs and cats to help reunite our furry friends with their families; an overview of the many programs and services of the Animal Defense League; a listing of various opportunities for you to become involved – as an ADL volunteer, as a foster parent and home for an animal not quite ready to be adopted; as a sponsor of an animal in our care; or as a financial donor.
