Large Breed Aging and Health
Large dogs face unique health challenges related to their size. Their rapid growth phase puts stress on developing bones and joints, which is why large breed puppies need specially formulated food with controlled calcium and phosphorus levels. As adults, large dogs are more susceptible to orthopedic issues like hip and elbow dysplasia. They also face higher risks of gastric dilatation-volvulus (bloat), a life-threatening condition. The Dog Aging Project, a major longitudinal study, is researching why large dogs age faster, examining factors from cellular metabolism to gut microbiome composition. Early findings suggest that larger dogs have higher concentrations of growth hormones, which may accelerate aging.
