In a groundbreaking study that involved an extensive survey and data analysis, researchers have discovered surprising factors that significantly impact the health and well-being of dogs. The study, conducted by the Dog Aging Project, found that a dog’s social support network has a fivefold greater influence on its overall fitness and longevity compared to financial conditions, household stability, or the age of its owner.
The research team surveyed a cohort of 21,000 dogs, revealing a strong correlation between increased social support and improved overall well-being in canines. These findings shed new light on the critical role that a dog’s environment plays in determining its lifespan and overall health.
Dr. Noah Snyder-Mackler, an assistant professor at the ASU School of Life Sciences, emphasized the significance of studying companion dogs to better understand the impact of social and physical environments on aging, health, and survival. Given the deep affection and care that people have for their dogs, coupled with their comparatively shorter lifespans, these furry companions offer a valuable model for investigating the effects of various environmental factors.
The study, which involved over 21,000 dog owners, was conducted by Arizona State University’s School of Life Sciences in collaboration with the Dog Aging Project, a large-scale community-science initiative led by the University of Washington and Texas A&M schools of medicine. The project aims to explore how genes, lifestyle, and the environment contribute to aging and disease outcomes in dogs, with over 45,000 dogs enrolled in the study across the United States.
The team, consisting of researchers Bri McCoy and Layla Brassington, alongside Dr. Snyder-Mackler, conducted an extensive analysis of the detailed survey data from dog owners. The survey covered various aspects, including physical activity, environment, dog behavior, diet, medications, health status, and owner demographics. Through this analysis, the researchers identified five key factors that contribute to a dog’s social environment and are associated with its well-being: neighborhood stability, total household income, social interaction with children, social interaction with other animals, and owner age.
Interestingly, the study found that a dog’s lived and built environment had a significant impact on its health, disease diagnoses, and physical mobility, even after accounting for the dog’s age and weight. Financial and household adversity were linked to poorer health and reduced physical mobility, while increased social companionship, such as living with other dogs, was associated with better health. Notably, the effect of social support on a dog’s well-being was five times stronger than that of financial factors.
The study also revealed some unexpected findings. Firstly, there was a negative association between the number of children in a household and dog health. Additionally, dogs from higher-income households were diagnosed with more diseases. The researchers suggested that dedicating more time to human children might lead to less time spent with furry companions, thereby impacting the dogs’ health. Furthermore, wealthier households had better access to medical care, resulting in a higher number of disease diagnoses due to increased veterinary visits and additional tests.
The researchers acknowledge that the survey data collected from dog owners may contain some error, bias, or misinterpretation. However, they are planning further investigations to explore the links between the survey results and underlying physiological mechanisms. By collecting biological samples from a subset of approximately 1,000 dogs over an extended period, they aim to delve deeper into how the environment influences dogs’ health at a cellular level.
Moving forward, the Dog Aging Project intends to incorporate electronic veterinary medical records, molecular and immunological measures, and at-home physical tests to obtain more accurate measures of health and frailty in companion dogs. Ultimately, the study highlights the profound impact of the social environment on health outcomes in both dogs and humans, emphasizing the need for increased attention to the role of the social environment in promoting healthier and longer lives.
