Dogs show behavioural and physiological responses to the loss of companion animals and humans that parallel grief responses in other species. Understanding these responses guides supportive care for bereaved dogs.
Whether dogs experience subjective grief equivalent to human emotional experience remains scientifically debated, but behavioural and physiological responses to companion loss are well-documented and represent genuine welfare concerns regardless of their phenomenological character. Dogs showing post-loss behavioural changes — reduced eating, sleep disruption, vocalisation, and reduced engagement with activities previously enjoyed — are experiencing a state that warrants welfare attention. Supportive interventions focus on maintaining routine and positive engagement: consistent feeding schedules, increased gentle exercise, and extended social interaction with familiar humans help buffer the disruption of social loss. Introducing a new companion animal too quickly may cause additional stress rather than comfort; timing should be guided by the individual dog's recovery rather than owner convenience. If behavioural changes persist beyond four to six weeks or are severe, veterinary assessment including a pain check and anxiety management consultation is appropriate.
