Dogs form deep attachments to human family members and companion animals. When these bonds are broken by death, dogs experience behavioral changes consistent with grief that require owner recognition and support.
Canine grief is real, neurologically measurable, and causes genuine suffering. The behavioral changes seen after companion loss — searching for the absent individual, reduced appetite, disrupted sleep, and social withdrawal — parallel mammalian grief responses across species. Owners who dismiss these changes as anthropomorphism miss an opportunity to provide supportive welfare interventions. Maintaining routine, providing gentle additional attention, and allowing the dog to grieve at its own pace are most supportive. Forcing social interaction or rushing toward a replacement companion often increases rather than reduces distress. Prolonged or severe grief that does not resolve within 4-6 weeks warrants veterinary consultation.
