Companion Animal Grief and Bereavement

Animals grieve the loss of bonded companions, and this welfare need deserves recognition and support.

Key Facts

Dogs and cats show behavioral changes after the death of bonded companions including reduced appetite and activity
Horses separated from bonded companions show elevated stress hormones and behavioral changes
Elephants in the wild spend extended time with the remains of dead family members
Many species form pair bonds whose disruption causes lasting behavioral changes
Grief in animals is increasingly recognized by behavioral scientists as analogous to human bereavement

Welfare Considerations

Animal grief is a welfare consideration that follows the loss of a bonded companion, whether that companion was another animal or a human. Dogs and cats that lose bonded housemates show behavioral changes — reduced activity, altered eating, searching behavior — that parallel human grief responses. These changes reflect genuine psychological distress that may require active support. Providing consistent routine, gentle interaction, and appropriate social opportunities supports grieving animals through the transition. In some cases, introducing a new companion may help, but timing and approach matter significantly for the grieving animal's welfare.
