Introduction: Robotic pets are technology-based interventions designed to foster engagement, emotional comfort, and companionship among people living with dementia, especially in residential care settings. Although prior research has explored stakeholders' experiences with existing robotic pet models, the design preferences of people living with dementia, their family members, and residential aged care staff remain poorly understood. Aim: This study investigates what these stakeholder groups look for in robotic pet design. Method: A descriptive qualitative approach was used. Semi-structured interviews were carried out with 11 participants, comprising 2 people living with dementia, 4 family members, 2 aged care managers, and 3 aged care staff. All interviews were audio-recorded, transcribed, and analysed through reflexive thematic analysis. Findings: Three key themes emerged: (1) fostering connection through design: familiar, realistic aesthetics with appealing features and interactive capabilities, such as subtle responsive movements and sounds, (2) enabling individualisation and inclusiveness: designs tailored to residents' preferences and prior pet ownership experiences, with appropriate size and weight for comfortable handling, and (3) balancing design with pragmatic considerations: practical features including convenient charging, ease of cleaning for hygiene maintenance, and affordability. Conclusion: This study offers practical insights to guide the development of robotic pets that more effectively meet the needs of people living with dementia and those who care for them. Preferred design features balanced the desire for meaningful connection with the practical demands of residential care environments.
