Summary
Animal shelters and humane organizations operate in a grant landscape dominated by private foundations and corporate philanthropies rather than direct federal funding. The most significant grant opportunities come from Petco Love, PetSmart Charities, the ASPCA, and state-level animal welfare funds. Federal funding is available indirectly through USDA programs, disaster response funding, and community development grants. This guide covers all major funding sources for animal welfare organizations in 2026.
Major Foundation & Corporate Grant Programs
Petco Love
The largest dedicated source of animal welfare grants in the US. Petco Love invests in partner organizations to save the lives of animals in shelters. Investments range from local shelter partnerships to major capacity-building grants. Apply through petcolove.org — they have rolling applications for smaller grants and annual cycles for major investments. Priority: reducing euthanasia rates and increasing adoptions.
PetSmart Charities
Awards grants of $5,000–$250,000 for programs focused on increasing pet adoptions, spay/neuter services, and pet retention (keeping pets with families). In 2026, priority areas include capacity building for under-resourced shelters, community cat programs, and safe housing for pets. Apply at petsmartcharities.org — grant cycles vary by program.
ASPCA Grants
The American Society for the Prevention of Cruelty to Animals funds animal welfare organizations through multiple grant programs: the Shelter Capacity Fund (equipment, training), the Anti-Cruelty Group (law enforcement/humane law enforcement), and strategic field grants for specific initiatives. Visit aspca.org/grants for current programs and eligibility.
Maddie's Fund
Maddie's Fund focuses on increasing the number of animals saved in shelters and rescue groups. Programs include community grants, shelter medicine training, and collaborative regional initiatives. They prioritize data-driven programs that can demonstrate measurable reductions in euthanasia.
Humane Society of the United States (HSUS) — Grants
HSUS funds local and regional animal shelters through its Rural Area Veterinary Services and state-specific programs. Focuses on rural communities with limited veterinary access and under-served shelter systems.
Federal Funding Sources for Animal Shelters
USDA APHIS (Animal and Plant Health Inspection Service)
USDA APHIS funds animal welfare research and enforcement activities, and occasionally funds cooperative agreements with organizations involved in animal care, disease prevention, and welfare research. Not a direct shelter grant program, but organizations involved in livestock welfare, feral cat management (rural), or zoonotic disease surveillance may find opportunities through APHIS.
HUD CDBG (Community Development Block Grants)
The Community Development Block Grant program funds a wide range of community services in low-income areas — and animal shelters serving low-income communities have successfully accessed CDBG funds for facility construction, renovation, and programming. Apply through your local CDBG entitlement community (city or county).
FEMA Disaster Response
During and after federally declared disasters, animal shelters providing emergency animal care may access FEMA funding through state emergency management agencies. Several states have also developed dedicated emergency animal shelter programs using FEMA preparedness grants.
State Animal Welfare Funds
Many states have dedicated animal welfare funding: California's Pet Lover's Spay/Neuter Fund, Colorado's Pet Overpopulation Fund, Florida's Animal Shelter Assistance Program, and similar state-level programs funded by license plate fees, donation checkoffs, or direct appropriations. Contact your state's department of agriculture for state-specific programs.

Grant-Readiness Checklist for Shelters
- Maintain current 501(c)(3) status — required for all major grants
- Track and report live release rate (animals adopted or transferred vs. euthanized) — all major funders require this data
- Register on SAM.gov if you plan to pursue federal or CDBG funding
- Document spay/neuter statistics — high-volume programs attract more foundation funding
- Apply to Petco Love and PetSmart Charities first — highest success rates for established shelters
