If you want to know how to calculate the age of the dog in human years, continue reading this article. We have all heard that dogs age quite quickly compared to man; It is common to find questions in front of pets like these: how many years can this dog live? Or what is Rocky’s life expectancy?
The common belief has always been that seven years of a human is the same as 1 year of a dog and that is why many times they do the calculations simply by multiplying the age of the dog by 7, but this is not the case, it is something totally inaccurate since Dogs reach adulthood at two years of age.
Knowing the age of a dog is not really easy, because it is not about multiplying the years by a single number, since its age does not pass as lightly in its first years of life or in adulthood. A one-year-old dog is equivalent to 15 years of age in men, but for example the second will already be equivalent to 9 years of age for man and when he reaches his adult stage the equivalence will be 4 years.
In these terms we can see that in the first two years of a dog’s life, it develops and grows rapidly and that later its aging process begins to slow down; therefore, depending on the chronological age of the dog, the calculation varies in relation to the human.
The average age of a small dog is 16 years old, so up to this point we will show you the equivalences, which we will detail in the following table, which also reaches the same age as an old man at 90 years old.
Table to calculate the age of the dog in human years
| The dog | The human |
| six months | five years |
| eight months | nine years |
| Twelve months | fourteen years |
| Eighteen months | twenty years |
| two years | twenty-four years |
| three years | Thirty years |
| four years | forty years |
| five years | Forty-two years |
| six years | forty nine years |
| seven years | forty nine years |
| eight years | fifty six years |
| nine years | sixty three years |
| Ten years | sixty five years |
| Eleven years | seventy one years |
| Twelve years | seventy five years |
| Thirteen years | Eighty years |
| Fourteen years | eighty four years |
| Fifteen years | eighty seven years |
| Sixteen years | Ninety years |
Clarifications
- It is important to clarify that this table is only approximations, since the theories vary a lot. Others make the account in this way: they say that the first two years are equivalent to 12 years of man and that from then on each year is equivalent to 4.
- The breed and size of the dog are also influential in the rate at which they age; small dogs generally live longer than large dogs but reach maturity much faster, only in their early years, while large dogs take longer to mature but are already considered elderly at 5 years, while the little ones are old when they reach 10.
- The age that a dog can reach is usually between 8 and 15 years; large dogs last less than small ones, even the latter with excellent care can reach 20 years. Medium-sized breeds have a middle ground in both their longevity and maturation.
- As a curious fact, we tell you that the dog that has lived the longest in history until today, reached the age of 29.
Calculate the age of a dog whose origin is unknown
- It is possible that you have adopted a dog or a puppy and you do not know its origin and therefore neither when was its year of birth, we can tell you that you can know an estimated age in the following way:
Look at his teeth, look at their growth or how much tartar he has, if he is 8 weeks old he will still have his milk teeth, if he is 7 months old he will have all his teeth still clean and white, if he has reached two years of age, his teeth will have a duller tone and the teeth located in the back begin to be somewhat yellow, if he is already between three and five years old you can notice worn teeth and a good accumulation of tartar, between six and ten years there will be more wear and some disease in your mouth, if you are already in your old age, that is between ten and fifteen years old, your teeth will be very worn, it will be normal for some to be missing and for trying to be very evident, in large amount.
To find out more exactly, take him to the vet so that he can do a physical examination of his joints, bones, muscles and his organs.
