Before you learn why large breed dogs live shorter lives, sit down

dogs They are inseparable friends of many humans and that is why their health and life expectancy increases even more. live long This is a standing advisory. It is noteworthy that the animal kingdom operates by the rule that the bigger you are, the longer you will live. However, there is one exception to this section and that is the domestic dog.

in that sense, Dog There is a household exception and it applies that “the younger you are, the longer you live.” It is worth underlining that live long The number of pets of humans and companion animals has increased significantly in recent years due to greater care supported by scientific advances. Small breeds, which are already long-lived, have gradually increased their survival due to better care and can live up to 17 to 18 years.

Due to the longevity of large breeds

Latest research examines the reasons for this difference live long And they found the cause: cancer. It turned out that dogs Older children were more likely to die from the disease at a younger age than younger children. Additionally, size-selective breeding may be the reason why larger breeds are more susceptible to cancer.

According to scientific studies, this reasoning is attributed to the relationship between one’s body size Dog and evolutionary delays in the body’s natural defenses, which cannot keep up with the animal’s rapid growth. This means that while your pet uses most of its energy in growing and maintaining a huge structure, it cannot invest it in everyday cellular repair to avoid tumor-inducing failures or promote protection against cancer. Is.

It is worth noting that this does not mean that dogs Older people age faster than younger people. But research showed that as the average body weight of breeds increased, cancer incidence rates also increased. However, scientists predict that, over time, larger breeds will evolve and develop better cancer-fighting genes, leading to longer life spans with smaller litters in the future.
