Separation anxiety is largely preventable through graduated independence training beginning in puppyhood, making early intervention far more effective than treating established anxiety later.
Separation anxiety is a welfare problem that is substantially preventable through appropriate early management. New puppies should not receive unlimited constant company but should be gently and progressively taught that being alone is normal and safe. Beginning with very short alone periods and extending them gradually, while ensuring the puppy is settled before leaving, creates secure independence. Owners who invest this time in the first weeks of ownership prevent the chronic and often severe suffering of established separation anxiety in adult dogs. Trainers and behaviourists increasingly emphasise early prevention as a public health priority for companion animal welfare.
