The old rule-of-thumb that one dog year equals seven years of a human life is not accurate. The ratio is higher with youth and decreases a bit as the dog ages. Depending on breed, a dog experiences the raging hormones of adolescence anywhere from eight months to two years or more. Generally, a dog of six has aged about as much as a 45-year-old human. At 10, she's like a human of 65; at 12, a human of 75; and at 15, a human of 90 and at age 14 a dog would be about 82
there are 123 days in a dog year which means it is not possible that 1 humanyear is 7 dog years.There are 4 and a half dog years in two human years.
