How old is a dog?

The age of a dog and the life expectancy
It has always been believed that a human year corresponded to 7 years of dog but this belief has become obsolete and currently there are other more reliable formulas to calculate the age of a dog .
But what is certain is that the age of a dog is not the only factor that determines the stage of a dog’s old age, beyond the years, will depend on the size of a dog and his breed . The life expectancy of a giant dog, such as São Bernardo, for example, is approximately 8 years, although they can live up to 10. In small dogs, which are also mutts, life expectancy can reach the age of 20 , although as we will see below there are dogs that have lived much more.
In medium-sized dogs, such as the Chow Chow, the average longevity is about 14 years. We can name two cases of longevity: the record is from Bluey, an Australian shepherd dog who lived 29 years between 1910 and 1939. But it is also of special mention the case of Pusuke, a Japanese dog, crusader of shiba-inu, who lived 26 years and 9 months.
In short, you will find much information on the life expectancy of some breeds on the Internet, but in fact a dog will live more or less time depending on his diet , physical activity, absence of diseases and very important, the affection he receives from his human family.
Why do mutt dogs have longer longevity?
Purebred or pedigree dogs have often been crossed uncontrollably, and in many cases they have been related to each other. This results in a high inbreeding , which is associated with genetic diseases such as hip dysplasia.
On the other hand, in mutt dogs the genetic variety is greatly increased, which reduces hereditary diseases. Although this influences the life expectancy of a dog, as well as its size, it is also very important to remember that proper care can significantly increase your life.
