Study Reveals Further Health Benefit Linked to Dog Ownership

Study Reveals Further Health Benefit Linked to Dog Ownership

In a groundbreaking Swedish study involving over 3.4 million people followed for 12 years, dog owners have been found to experience significantly lower rates of cardiovascular disease and death compared to their pet-free counterparts [1]. This research, along with numerous other studies, reveals the scientifically proven cardiovascular benefits of dog ownership.

The heart-healthy effects of dog ownership extend beyond the psychological, as researchers propose that the benefits might be more physical than psychological, with dogs making us move [2]. The combination of physical, psychological, and social benefits offered by dog ownership contributes to better cardiovascular health.

Single dog owners, in particular, stand to gain amplified advantages due to their greater risk of isolation and reliance on pets for social and mental support [1][2][3]. The benefits of companionship and increased activity offered by dog ownership are most impactful when the person is otherwise socially isolated.

The lower cardiovascular disease risk associated with dog ownership is due, in part, to increased physical activity. Owning a dog encourages regular walks and outdoor activity, which boosts aerobic exercise levels [1][2][4]. This increase in daily physical activity is a key factor in improving heart health by lowering blood pressure, reducing cholesterol and triglycerides, and improving overall cardiovascular risk profiles.

Single dog owners showed a 33 percent reduction in overall mortality risk and 11 percent lower heart attack risk compared to singles without dogs [1]. Among heart attack survivors, those owning dogs had a better survival rate, suggesting dog ownership aids recovery and secondary prevention [2].

Single people living alone with dogs saw their risk of death drop by a whopping 33 percent compared to solo dwellers without canine companions [1]. The study identified increased human interaction as a potential mechanism for the cardiovascular benefits of dog ownership, as dog ownership frequently leads to increased social connections [5].

Furthermore, the study revealed intriguing variations in health outcomes based on both living situation and dog breed, suggesting that how we interact with our dogs significantly influences the health benefits we receive [6]. Working and hunting breeds, such as terriers, retrievers, scent hounds, and pointers, require more vigorous exercise and longer walks, translating to greater physical activity for their owners [6].

For individuals prone to stress-related cardiovascular issues, the calming presence of a dog might provide a meaningful physiological buffer against the harmful effects of chronic stress [7]. The study found that people with hunting breeds showed the lowest rates of cardiovascular disease [6].

The American Heart Association recognised a connection between pet ownership and better survival rates of coronary artery disease in a 2013 statement [8]. The study also showed that dog owners had better survival rates following cardiac events [2].

In addition to the cardiovascular benefits, other research suggests that dogs provide additional health benefits, such as improved mental health, better cognitive function in seniors, earlier disease detection, and faster recovery for hospital patients [9].

In essence, dog ownership offers a multifaceted approach to better health, with singles gaining amplified advantages due to their greater risk of isolation and reliance on pets for social and mental support [1][2][3]. The study suggests that our household environments significantly impact our microbiomes, and dogs might diversify our microbiomes in beneficial ways [10]. The average dog owner walks their pet for 22 minutes twice daily, which is nearly 5 hours of additional exercise over a week, more than enough to meet the American Heart Association’s recommendation of 150 minutes of moderate activity weekly [11]. The study affirms the value of daily walks for both the pet's benefit and the owner's cardiovascular health [12].
