Overview

Maddie's Fund, formally known as The Duffield Family Foundation (EIN: 94-3362163), was established in 1994 by Dave and Cheryl Duffield, co-founders of PeopleSoft and Workday, as a promise to their beloved miniature schnauzer, Maddie. The foundation celebrated its 30th anniversary in 2024, having awarded over $301 million in grants to animal welfare organizations nationwide. With assets of approximately $260-281 million and annual giving around $11.8 million, Maddie's Fund operates as the nation's leading family foundation focused exclusively on companion animal welfare. The organization's mission is to create a no-kill nation where all healthy and treatable shelter dogs and cats are guaranteed a loving home. In recent years, the foundation has evolved its strategy to focus on keeping pets and people together through community-centric programs, access to veterinary care, and reducing barriers to pet ownership. The foundation made 295 grant awards in 2024, supporting organizations ranging from small community-based groups to major national partnerships.

Specific decision timelines vary by grant program and are not publicly standardized across all grant types. Applicants should expect communication based on the specific program guidelines.

Success Rates

With 295 awards made in 2024, 263 in 2023, and 272 in 2022 from an undisclosed number of applications, specific success rate percentages are not publicly available. However, the foundation notes that due to high application volume, they may not be able to follow up on incomplete applications.

Reapplication Policy

No specific reapplication policy or waiting period for unsuccessful applicants is documented in public materials. Organizations should contact the Grants Team directly to inquire about reapplication after an unsuccessful attempt.

Application Success Factors

Understand Eligibility Requirements First: Organizations must be U.S.-based 501c3 public charities or government animal well-being organizations focused exclusively on dogs and/or cats. Ensure you publicly share annual statistics on your website, and if you shelter pets, share relevant intake/outcome benchmarks.

Contact Before Submitting: Maddie's Fund specifically encourages organizations to reach out with questions before submitting applications, as changes after submission may not be permitted. Use this opportunity to clarify alignment with program priorities.

Match Your Needs with Funder Priorities: Successful proposals demonstrate clear understanding of the seven basic elements of grant proposals and how organizational needs align with Maddie's current strategic priorities around keeping pets and people together, reducing barriers to care, and community collaborations.

Be Complete and Thorough: Due to high application volume, incomplete applications may not receive follow-up. Ensure all required information is included before submission.

Demonstrate Community Impact: The foundation "tends to support smaller, community-based groups that have a large and positive impact on the lives of dogs and cats in their communities." Emphasize local impact and community-centric approaches.

Show Innovation and Creative Thinking: Maddie's Fund actively seeks "innovative solutions and creative thinking through inclusive and community-centric programs and projects." Highlight novel approaches or expansions of proven programs.

Data-Driven Approach: Organizations that collect, report, and utilize data to inform decisions align well with Maddie's focus on "data-driven decision making." Demonstrate your commitment to transparency and measurement.

Watch Informational Resources: The foundation provides webcasts and educational materials about their application process—utilizing these resources demonstrates seriousness and preparation.

Participate in Community: Engagement in Maddie's Community Conversations (Monday Zoom sessions) and Pet Forum not only provides grant opportunities but also demonstrates commitment to the broader animal welfare community.

Recent Funding Examples: Study recent grantees like Palm Valley Animal Society, Santa Rosa County Animal Services, San Diego Humane Society, Kansas City Pet Project, Atlanta Dog Mom Full Hearts, Every Dog Behavior & Training, Good Shepherd Humane Society, and AlignCare Project to understand what types of organizations and programs receive funding.

Key Takeaways for Grant Writers

Multiple pathways to funding: With grants ranging from $3,000 to over $1 million across various programs, organizations of all sizes can find appropriate funding opportunities—but must apply to the right program for their needs and organizational capacity.
Strategic timing matters: Because grant programs have specific application windows that vary throughout the year, joining the mailing list and monitoring the grants portal regularly is essential to not missing opportunities.
Relationship building is valuable: The Community Conversations program (weekly Monday Zooms) offers both grant opportunities and networking—with 200+ live participants weekly, these sessions provide visibility and connection to the foundation's priorities.
Data transparency is non-negotiable: Public sharing of annual statistics and shelter benchmarks is a requirement, not a preference—ensure your organization is prepared to meet this standard before applying.
Community impact over organizational size: The foundation explicitly favors "smaller, community-based groups that have a large and positive impact," suggesting strong local outcomes can outweigh organizational scale or budget size.
Pre-submission consultation is encouraged: Unlike many funders, Maddie's Fund actively welcomes questions before submission—take advantage of this to strengthen your application and confirm alignment with program goals.
Focus on the human-animal bond: Applications should emphasize "keeping pets and people together" and reducing barriers to care, reflecting the foundation's evolved mission beyond traditional shelter lifesaving to broader community well-being.
