One year of dog life is equivalent to 18 years of human life. At this time, the dog becomes an adult. Usually dogs can live for about 12-14 years, so when a dog reaches about 8 years old, it is very old and its various body functions will also deteriorate. At this time, the owner must take good care of the dog, otherwise the dog will easily die of disease.

Generally speaking, the life span of a dog is about 15 years, but for hunting dogs or competition dogs with vigorous action, their life span is shorter. Dogs raised at home usually live longer, some reaching 20 years old.
