Dogs show clear behavioral responses to the death of bonded companions, with evidence of grief-like states that require welfare-conscious management by owners and veterinarians.
Canine grief represents a welfare consideration that has been systematically underestimated by both owners and veterinary professionals. The behavioral changes associated with loss of a bonded companion involve real alterations in emotional state, appetite, sleep, and activity that indicate reduced wellbeing. The welfare approach requires acknowledging this grief as genuine rather than dismissing it as behavioral inconvenience, providing appropriate support through consistent routine, increased positive interaction, and professional guidance when grief responses are severe or prolonged. Premature replacement of a deceased companion before a grieving dog has adjusted can also create welfare problems through difficult introductions.
