Why do dogs have a shorter lifespan than humans?

Introduction to the topic of canine longevity

Dogs are known for their loyalty, companionship, and unconditional love towards their owners. But unfortunately, their life span is much shorter than that of humans, and this has been a topic of interest for many years. The average lifespan of a dog varies based on several factors, including breed, size, and genetics. The question remains, why do dogs have a shorter lifespan than humans?

Comparison of human and dog lifespans

The average lifespan for a dog is between 10-13 years, while humans can live up to 80 years and beyond. This means that a dog reaches its senior years by the age of seven. The aging process in dogs is much faster than in humans, and this is due to several factors. The first is that dogs reach sexual maturity much quicker than humans, which means their bodies age faster. The second is that dogs experience accelerated aging, which means that the signs of aging appear much earlier in their lives. While humans can develop age-related diseases in their later years, dogs can develop these diseases much earlier in life.
