Preventing separation anxiety through appropriate early learning experiences during puppyhood is far more effective than treating established separation-related distress in adult dogs.
Preventing separation anxiety is a developmental welfare priority that requires planning from the first days of puppy ownership. Puppies that never experience brief, positive separation from owners during the sensitive period fail to develop the emotional resilience needed to cope with normal adult life including owner absences. The pandemic puppy cohort demonstrated this at scale: dogs acquired during lockdowns when owners were home constantly had dramatically elevated rates of separation anxiety when owners returned to work. The welfare cost of established separation anxiety is high — chronic daily distress — and treatment is prolonged. Prevention through early positive alone-time training is the most effective welfare intervention.
