Laid back dogs live longer, study says
We all know that small dogs generally live longer than big dogs, but a new study in Canada suggests that docile, obedient, shy dogs dogs are prone to longer lives than unruly, disobedient, bold ones.
Vincent Careau at the University of Sherbrooke in Quebec compared data from previous studies of personality in a number of dog breeds, and mortality data on the same varieties, and used additional data from insurance companies to come up with the conclusion.
Careau’s team found the most obedient breeds, such as German shepherds, poodles and bichon frises, tended to be the longest lived, while hard-to-train, high energy dogs such as pomeranians and beagles were more likely to die younger.
Another trait, aggressiveness, was linked to metabolic rate, with docile dogs such as collies burning calories more slowly than more territorial breeds, for instance .
According to a study abstract, “we tested whether proactive personalities (high levels of activity, boldness, and aggression) are related to a fast “pace of life” (high rates of growth, mortality, and energy expenditure)…
Being a shy, slow burner of calories myself, I can only hope the phenomenon applies to humans as well — for it means if I watch enough TV, take enough naps and avoid chasing squirrels, I will live longer than all of you doing your daily aerobics.
