Maddie’s Fund^® is a family foundation established in 1994 by Dave and Cheryl Duffield, and is the fulfillment of a promise to their inspirational dog, Maddie. Between 2005 and 2011, Maddie’s Fund provided grants totaling more than $26 million to the Alliance to fund the Maddie’s Pet Rescue Project in NYC and Maddie’s Spay/Neuter Project in NYC to help the Alliance end the killing of healthy and treatable shelter dogs and cats community-wide. The Alliance was the largest Maddie’s Fund community project in the United States.

Additionally, in 2011, Maddie’s Fund provided a one-year grant for the Maddie’s Spay/Neuter Project for Stray Community Cats in NYC to provide free spays and neuters for feral and stray cats and kittens in New York City for Certified TNR Caretakers. 

In 2013 and 2014, the Alliance hosted Maddie’s Pet Adoption Days in New York City. This national event, sponsored by Maddie’s Fund and billed as the largest free pet adoption event in America, resulted in more than 8,500 adoptions by participating organizations in the NYC area. The Alliance and all the groups that participated in the events are grateful to Maddie’s Fund for helping to find new homes for so many Little New Yorkers.
