Best Friends Animal Society
At Best Friends Animal Society, our goal is to get more dogs and cats out of shelters and into homes and make every shelter in America no-kill. No-kill isn’t just possible, it’s within reach. Today, more than 2 out of 3 U.S. shelters are no-kill, and hundreds more are within reach of that goal. With your help we can finish the work we started and save every at-risk pet and secure a better future for our best friends. Since 2016, when Best Friends committed to leading the nation to no‑kill, around 40 million dogs and cats have been saved in America’s shelters. Behind that number is the power of an entire movement—animal shelters, rescue groups, volunteers, community advocates, and people like you—working together year after year to save homeless pets.
