The "Protecting America’s Working Dogs Act of 2026" aims to address the medical needs of retired working dogs by establishing a grant program. The program, administered by the Attorney General, will provide grants to eligible nonprofit organizations to cover medical expenses for qualified working dogs, including those retired from the federal government or serving veterans. The bill sets criteria for nonprofit eligibility and requires reporting on the use of funds and the number of dogs assisted. It defines covered medical expenses and outlines the responsibilities and requirements for eligible nonprofits. The bill emphasizes the critical role these dogs play in safeguarding national security and the well-being of their human partners.
