Scientific observations of grief-like behaviour in animals have important implications for how we understand animal emotional lives and welfare needs during bereavement.
Animal grief evidence expands our understanding of the emotional depth of non-human animal lives. If animals experience something functionally equivalent to grief — behavioural and physiological responses to loss of bonded companions — then bereavement is a welfare consideration that demands attention. This means that the death or removal of a bonded companion is not a neutral event but one that requires careful management: allowing time with a deceased companion, maintaining familiar social structures, providing extra care during the adjustment period. The welfare implications extend to farm animal management, where the routine separation of bonded animals is rarely managed with grief in mind, and to companion animal care where owner death or euthanasia may require more active welfare support for surviving pets.
