How do you protect those who spend their lives protecting others? Nurses provide care in the most vulnerable hours of human life, yet they often face situations where their own safety is compromised.
Tensions can rise in emergency rooms, visitor disputes can escalate, and the late-night quiet of hospital corridors can be unsettling. Security guards and systems have their place, but some solutions offer more than physical protection.
Dogs have been trusted protectors for centuries, combining instinct, loyalty, and deterrence in ways humans cannot replicate. The right breed can provide a watchful presence without disrupting the delicate balance of a medical environment.
