Free Spay/Neuter Services

To our valued supporters: Due to shifting needs on ADL resources, ADL is temporarily unable to accept any SAFCC or community owned animals qualifying for subsidized sterilizations. Until further notice, limited dates will be posted as they become available. We apologize for any inconvenience and look forward to resuming services in our efforts to best support the community.
