Companion Animal Grief and Loss Psychology

Companion animals experience grief when they lose bonded companions, requiring welfare consideration in multi-pet households and during bereavement.

Key Facts

Animals showing reduced engagement, appetite changes, and increased vocalization after losing companions are experiencing negative emotional states that affect quality of life. Owners who understand companion animal grief can provide appropriate support through increased interaction, maintained routine, and careful decisions about whether and when to introduce new companions.
