Social isolation is one of the most significant welfare threats to companion dogs, with chronic aloneness causing behavioral and physiological stress.
Dogs evolved as social animals living in continuous contact with human and dog companions. Requiring them to spend 8-10 hours alone daily is fundamentally incompatible with their social nature. Separation anxiety represents the extreme end of isolation distress, but all dogs are affected by chronic aloneness to some degree. Pre-adoption assessment of lifestyle compatibility and commitment to addressing isolation is an ethical obligation when acquiring a social species.
