Animals grieve the loss of companions and family members, and understanding this helps owners support their pets through loss.
Animals that form strong social bonds suffer genuine distress when those bonds are broken by death. The welfare impact of losing a long-term companion can be profound - reduced appetite, altered sleep, increased stress hormone levels, and behavioral withdrawal. Owners who dismiss animal grief as anthropomorphism may fail to provide appropriate support. Companion animals should not be forced to interact with new animals before they are ready - grief has a process that deserves respect. End-of-life decisions for terminally ill animals should consider the welfare impact on surviving companions. Some animals benefit from seeing or smelling the body of a deceased companion.
