The age of a dog is calculated according to human age. Usually eight months is equivalent to about fifteen years of human life, and one year is equivalent to eighteen years of human life. From then on, four years are added every year until eight years old. A dog's age is equivalent to a person's fifty years old, which means they have entered old age. Dogs who are one or two years old are often the most energetic.

Tip:

After dogs enter old age, we should change the way they are raised, give them more food high in calcium, and exercise appropriately every day.
