Companion animals experience genuine grief responses when losing bonded partners or owners, and supportive care helps them navigate loss.
Animal grief is now well-documented scientifically, moving beyond anecdotal accounts to physiological and behavioral evidence. Dogs and cats form genuine attachment bonds with both humans and other animals, and loss of those bonds triggers responses parallel to human grief: searching for the absent individual, reduced motivation, altered sleep, and social withdrawal. Supporting a bereaved animal involves maintaining routine (which provides comfort through predictability), providing additional gentle interaction, monitoring food intake, and allowing time for adaptation. Veterinary support may be needed if grief responses persist or if an animal completely stops eating. The recognition of animal grief has welfare implications beyond individual cases — it reinforces the importance of managing group housing and companion pairing with the understanding that loss causes real suffering.
