How Many Dog Years Equal One Human Year?

How Many Dog Years Equal One Human Year?

The first two years of a dog’s life equal about the first 24 years of a human’s life. After that, each year of a dog’s life equals about four “people” years. Most 13-year-old people still feel like kids at that age. But at the age of 13 years, a dog is already an old-timer. A 13-year-old dog compares in age with a man or woman of 68 to 70 years.

As with humans, advanced years often bring changes in a dog’s ability to hear, see and move about easily. Skin condition, appetite and energy levels often degrade with geriatric age, and medical conditions such as cancer, renal failure, arthritis and joint conditions, and many other signs of old age may appear.

Every kind of animal has a different life span. One of the shortest-living animals is the mayfly, which lives only a few hours. The animal that lives the longest is the tortoise. It can live 150 or more years.
