Psychiatric nurses are expert care providers for individuals with mental health needs. The art of caring spans across multiple species, is important to understand, and is universal whether intentions are toward individuals or animals. Pets are often cared for and viewed as family members. The current research examined psychiatric nurses' views on the similarities and differences of caring for patients and their pet dogs. Twenty-five nurses were interviewed. Similarities of caring for patients and canines included trusting relationships, companionship, daily basic needs, and improved communication through monitored body language. Differences in caring included personal expectations, unconditional love, and professional boundaries. Understanding the concepts of caring for patients and pet dogs will provide the opportunity for insight into familial versus professional relationships, improve communication with others, and strengthen the human-animal bond.
