Companion Animal Grief and Loss | Animal Welfare Hub

Dogs and cats show behavioral and physiological responses to the death of bonded companions, and supporting grieving animals requires understanding these responses and appropriate management.

Key Facts

Dogs show measurable changes in behavior following the death of a bonded companion including reduced appetite and activity
Cats show changes in vocalization, searching behavior, and social patterns following companion loss
Cortisol elevation has been measured in surviving animals following companion death
Some animals appear to benefit from viewing the body of a deceased companion in reducing searching behavior
Introduction of a new companion requires careful timing and introduction management

Welfare Considerations

Companion animal grief responses are genuine welfare events that owners frequently underestimate or misinterpret. Reduced appetite, increased vocalization, and searching behavior in surviving animals reflect the loss of a significant social relationship. Supporting grieving animals involves maintaining routine while allowing behavioral expression of the loss, monitoring for health effects of reduced food intake, and thoughtful timing of any new companion introductions. Forcing new introductions before an animal has adjusted can compound rather than resolve the welfare impact.

What You Can Do

Allow grieving animals space and time to adjust following a companion's death
Maintain consistent routines to provide stability during a companion loss period
Monitor food intake and health closely in the weeks following a companion's death
Consult your veterinarian if a grieving animal's appetite reduction becomes a health concern
