Separation anxiety is one of the most common and welfare-significant problems in dogs. Prevention through graduated independence training from puppyhood is far more effective than treating established anxiety.
Separation anxiety causes dogs to experience repeated acute fear during what may be the majority of their waking hours if owners work full time. A dog experiencing panic for 8 hours daily is living a profoundly compromised life regardless of the quality of care during the hours the owner is present. Prevention through graduated alone-time training during the sensitive puppy period is highly effective and requires modest time investment. When anxiety does develop, early treatment prevents progression to severe forms that are harder to manage. Recognising separation anxiety as a welfare emergency rather than a nuisance behaviour is essential to motivating appropriate intervention.
