Dogs, cats, and other companion animals demonstrate clear behavioral signs of grief following the loss of bonded companions, yet this aspect of animal welfare remains underrecognized.
The grief experienced by animals following loss of companions represents a form of emotional suffering that science increasingly confirms is real and significant. Animals that have formed strong social bonds show measurable physiological and behavioral responses to loss that parallel grief in humans. While these animals cannot articulate their loss verbally, the suffering is no less genuine. Supporting animals through bereavement — through consistent routine, gentle engagement, and veterinary support if needed — is an important component of responsible animal care.
