The main purpose of this legislation is to create a pilot program within U.S. Customs and Border Protection (CBP) that focuses on adopting dogs from local animal shelters. These dogs will be trained to serve as support dogs for CBP personnel. The initiative aims to provide emotional support and companionship to those working in the agency, helping to improve their well-being and mental health. Key provisions of the legislation include the requirement for the Secretary of Homeland Security to set up this pilot program within 60 days of the law's enactment.
