Why don't great danes live longer?

Great Danes have shorter lifespans compared to smaller Dog Breeds primarily due to their large size, which predisposes them to various health issues. Their rapid growth can lead to skeletal problems, and they are also more susceptible to conditions like dilated cardiomyopathy and bloat. Additionally, the metabolic and physiological demands of their size can strain their organs, contributing to a shorter lifespan. Overall, while they are gentle giants, their size presents unique health challenges that limit their longevity.
