Who could benefit from this research

Could help

Ideal candidates for this research are children aged 0-11 years who have recently adopted a pet dog.

Less likely to help

Patients who do not have a pet dog or are not within the specified age range may not benefit from this research.

What this research studies

This research investigates the development of social bonds between children and their pet dogs over time, focusing on how these bonds can positively impact child health and wellbeing. The study will measure the strength of these bonds at four different time points after a dog is adopted, using behavioral tasks and biological samples to assess changes in oxytocin and cortisol levels. By examining the relationship between social bond strength and brain responses, the research aims to uncover the mechanisms that contribute to the therapeutic effects of pet ownership for children.

Why it matters

Potential benefit: If successful, this research could enhance our understanding of how pet dogs can support children's emotional health and development.

How similar studies have gone: Previous research has shown promising results regarding the benefits of pet ownership on child development, making this study a valuable continuation of that work.
