Animals are integral to service ecosystems, aiding in health care, accessibility, social engagement, and leisure. Despite their significant roles, the specific value outcomes of animal-based services—economic, psychological, societal, and environmental—are under-examined. This chapter investigates therapeutic, personal assistance, social engagement, and recreational services, categorizing them by purpose (health care vs. entertainment) and caretaking arrangements (service provider vs. individual consumer). It highlights the need for stronger policies and self-regulatory business practices to ensure fair treatment of service animals, as current protections are limited. Given their economic contributions, animals should be safeguarded through regulations on training, certification, and welfare, including humane handling and stress monitoring. Legal inconsistencies complicate protections for working animals, who, unlike human workers, do not receive direct compensation, raising welfare concerns. Policymakers could mandate financial provisions for animals’ health care and retirement. Ethical reflection on animal agency and consent is crucial, as service roles may involve non-voluntary participation. Promoting humane training and transparent welfare protocols can enhance trust in animal-based services and encourage responsible practices.
