Companion Animal Grief and Loss | Animal Welfare Hub

Dogs and cats experience genuine grief following the loss of companions, and recognizing and supporting animals through bereavement improves their welfare significantly.

Key Facts

Welfare Considerations

Animal grief is a recognized behavioral and physiological state involving altered corticosteroid levels, reduced motivation, and behavioral depression. Dogs and cats form genuine social bonds whose loss creates a real bereavement response. Owners who themselves are grieving may inadvertently reduce interaction with surviving pets at the time when connection is most needed. Understanding companion animal grief helps owners provide appropriate support through routine, gentle interaction, and veterinary monitoring.

What You Can Do

Maintain daily routines for surviving pets after the loss of a companion animal
Consult a veterinarian if grief responses persist beyond several weeks or affect eating
Provide gentle extra attention and enrichment to bereaved pets
Consider a gradual introduction to a new companion when timing feels right for both pet and owner
