Separation anxiety in dogs causes acute distress during owner absence and can lead to destructive behaviour, self-injury, and chronic stress, but responds well to evidence-based behavioural and medical treatment.
Dogs with separation anxiety experience genuine panic when left alone - elevated heart rate, cortisol, and behavioural distress are physiologically equivalent to extreme fear. Each departure triggers the same panic response regardless of duration. This is not naughty behaviour but genuine psychological suffering that owners must take seriously. Punishment for separation-related destruction is counterproductive and harmful. Systematic desensitisation - gradually increasing absence duration - is time-intensive but effective. Medication alongside behaviour modification produces better outcomes than either alone in severe cases.
