This is a common way to convert dog age to human age. However, as studies have shown, this formula is not very accurate. According to the latest research in 2020, the age of a dog is actually a bit more complicated than this.
The study investigated the growth of 104 Labrador puppies and analyzed the rate of aging. He found that the puppies actually age much faster than humans when they are young, and the rate gradually declines as they get older. The formula for this conversion is “dog age = 16 * ln (human age) + 31”, or “human age = e^(dog age-31)/16”.
Do you think this formula is too complicated? No worries! The following is the conversion between human age and dog age:
3 months old for dogs = 9 years old for humans
6 months old for dogs = 20 years old for humans
9 months old for dogs = 26 years old for humans
1 years old for dogs = 31 years old for humans
2 years old for dogs = 42 years old for humans
3 years old for dogs = 49 years old for humans
4 years old for dogs = 53 years old for humans
5 years old for dogs = 57 years old for humans
6 years old for dogs = 60 years old for humans
7 years old for dogs = 62 years old for humans
8 years old for dogs = 64 years old for humans
9 years old for dogs = 66 years old for humans
10 years old for dogs = 68 years old for humans
11 years old for dogs = 69 years old for humans
12 years old for dogs = 71 years old for humans
13 years old for dogs = 72 years old for humans
14 years old for dogs = 73 years old for humans
15 years old for dogs = 74 years old for humans
16 years old for dogs = 75 years old for humans
17 years old for dogs = 76 years old for humans
18 years old for dogs = 77 years old for humans
19 years old for dogs = 78 years old for humans
20 years old for dogs = 79 years old for humans
This conversion is suitable for all dogs, so you can directly compare the ages~ Share with us your thoughts down below!
