There is a special emotional bond between humans and their pets. In modern society, pets have become emotional family members rather than utilitarian objects, fulfilling human needs for belonging, security, and intimacy. However, since pets' lifespans are shorter than humans', the impact of pet death cannot be overlooked. This article explores owners' grief reactions and adjustment processes from the perspective of life education, analyzing how life education can help owners face loss, complete mourning, and reconstruct meaning. The findings reveal multifaceted grief reactions across emotional, cognitive, physical, and behavioral domains. Grief intensity is related to attachment strength, cause of death, and social support. Grief adjustment is a dynamic process involving impact, pain, and reconstruction stages. Coping strategies include facing emotions, sublimating grief, modifying cognition, and performing mourning rituals. Emerging digital memorials also contribute to meaning reconstruction. Life education can assist owners through five dimensions: understanding life and death, learning grief expression, participating in mourning rituals, seeking social support, and giving meaning to death. Suggestions include integrating pet-related issues into life education curricula, establishing support networks, and providing professional training to promote societal attention to pet loss issues.
