Companion animals grieve the loss of bonded companions, and owner recognition and management of grief responses significantly affects welfare during bereavement.
Companion animal grief is real and measurable, reflecting the genuine social bonds that domesticated species form with companions. Surviving animals benefit from stable routine, increased positive human interaction, and maintained enrichment during the grieving period. Owners who mistake grief signs for illness may undertake unnecessary veterinary intervention; awareness of normal grief responses reduces this. Replacement with a new companion should only occur when the surviving animal has sufficiently recovered, typically assessed by return to baseline behaviour.
