How Old in Human Years Is an 8-Year-Old Dog?

An 8-year-old dog is about 50–65 in human years. Because small breeds generally live longer than large ones, a small dog’s 8 years is about 50–55, a medium about 60, and a large about 65. At 8 any dog is a senior, so adjust its diet to soft, digestible senior food.

Also, avoid intense training and reduce climbing and jumping to protect aging joints.
