This list represents organizations that we examined in some way during our recommendation process. We have categorized each organization by their type of work and status. In total, we have considered over 170 animal organizations, conducted shallow investigations on 76 charities, and conducted a deeper analysis of 18 charities. We also considered three organizations which requested not to be listed here.
It is important to note that the small number of highly recommended organizations below is the result of a deliberate decision to provide clear and actionable recommendations to donors who are seeking to find the highest impact uses for their donations. We believe that many more of the animal organizations listed below also do excellent work on behalf of animals.
For more recent thoughts on sanctuaries, including their values and how to maximize their impact, see our blog entry from September 24, 2015.
* Declined to be reviewed.
† Voluntarily removed from consideration, usually due to donations made to ACE from organizational leadership.
‡ Not considered because the group falls outside our scope of consideration or because of a conflict of interest.
