1 year of a dog is equivalent to 7 human years? False

It is common to hear that a year of a dog's life equals seven years in the life of a human. This is a false, rather inaccurate estimate of how dogs actually age.

For starters, not all breeds of dogs live the same number of years Therefore, calculating their life expectancy with a simple multiplication by seven will not solve the question of how many years our dog will live.

In order to better understand this aspect, we must take into account that during the first 12 months of life, the dog reaches an age of 12 years. compared to that of humans. For the next two years, the pet continues to develop and from then on, its aging slows down.

For more accurate data, for the first two years of the dog's life we are going to have:

  • 12.5 human years for each year of life of a small puppy
  • 10.5 human years for every year of life of an average-sized dog
  • 9 human years for each year of life in the case of the large ones.

From the age of two years, every 365 days of the animal's life must be multiplied by a factor of between 4.3 and 13.4 years depending on the breed of the dog.

Cross-bred dogs live an average of 1.22 years longer. than purebreds, a factor to take into account if we want our best friend to stay with us as long as possible.

Tell us your dog's name and current age, we'd love to know.

Table to calculate age of dogs

Everything we have seen in the previous point can be summarized as follows table that will allow you to calculate the age of a dog in human years depending on its size, whether it is a small, medium or large breed.

As you can see, the life expectancy of a dog decreases with increasing size. When the end of the pet's life expectancy is near, it can be seen that a giant breed has many more human years than a small one and, logically, this causes a series of problems for the animal.

In short, large dogs tend to live shorter lives than the small ones.

How can you know your dog's age if you don't know it?

We do not always know the age of a dog, something quite frequent in abandoned or foster dogs. In these cases there are a number of clues that can give us an idea of how old it may be the animal.

The teeth are usually the first thing to be examined The teeth of a dog change a lot over the years, especially in the first months of life:

  • 2 to 3 weeksno teeth
  • 4 weeks: temporary fangs or canines begin to erupt
  • 4 to 6 weekspremolars and primary incisors: premolars and primary incisors erupt
  • 8 weeksThe dog already has 28 temporary teeth that will fall out in the next few weeks.
  • 4 to 5 monthsTemporary teeth are falling out and the permanent teeth are starting to erupt.
  • 6 monthsThe dog has 42 permanent teeth and his teeth are so white and clean.
  • Between 2 and 4 years of age teeth become yellower and tartar starts to appear.
  • From 5 to 9 years old: tartar buildup increases and teeth become even more yellowish
  • From 10 to 15 years old: the animal may have lost some teeth and its appearance is yellowish with a lot of wear and tear.

Below you have an infographic elaborated by the Instituto del Perro in which you can see graphically the evolution of the dentition in a dog to calculate its age:

Then there are other details that can help us know how old my dog is. His physical and muscular condition or the condition of your hair will help us to draw more accurate conclusions.

Remember that a dog when young it has very fine hairThey have a fluffy, fluffy type, which is why they look so similar to stuffed animals. As they grow, the dog's hair becomes thicker and coarser, even gray hair appears on the muzzle and head area if they are already advanced in age.
