How do you know the real age of dogs and how many years can they live?
Whoever reaches his dog ten years old knows that this pet's life may be equivalent to the age of a man who has been in the long term for more than 70 years, by calculating that each year of the dog's age equals seven years of human life, and it is the calculation that was reached considering that the average age of humans is 77 years old, while the average dog age is about 11 years.

However, new research finds that things are not so simple, and given some prominent signs of growth, the reason is clear. For example, most breeds of dogs reach sex between the ages of six months and a year - and by taking the maximum and corresponding with the traditional method of calculation, puberty will correspond to seven years in human life... Moreover, the life of dogs can sometimes extend, if rarely, to 20 years, and if we apply one rule to seven it will be equivalent to 140 years in humans, which is unrealistic.

The average lifespan of a dog is largely dependent on its breed, as smaller dogs are usually longer lifespans, which means that they age more slowly than larger dogs.

All this raises a question about what is meant specifically by age. Perhaps the direct way to calculate age is the number of years from birth, which is called the time definition of age. However, there are other definitions of age, such as biological age. It is a subjective definition that relies on the evaluation of physiological indicators to monitor an individual's growth and development, including measurements such as a "debility index" - which takes into account the health status of the individual and the extent of his impairments, cognitive ability and level of activity.

There are also biological indicators of aging based on more objective foundations, such as levels of gene expression (as genes produce specific proteins at varying rates at different ages) or the number of immune cells. The biological life expectancy rate also depends on hereditary factors, as well as on the mental health and lifestyle of the individual.

For example, a person who eats a lot of harmful food, smokes a lot, and does not exercise, exposes himself to increasing his biological life over his lifetime. You may also be aged 60 years, while your body condition is 40 years if you take good care of yourself.

And when we talk about comparing the ages of animals of different types, biological definitions benefit more than calculating the time age. When we are told that a six-week-old pet mouse, does not give us a good picture of what stage the mouse has reached in his life even if we know that the mice live in The average is three years. But when we know that the mouse has reached reproductive and reproductive age, it gives us a clearer picture of its maturity.

The authors of the new study see the validity of calculating the biological age through what is known as a "genetic clock", meaning changes related to DNA that accumulate over time in mammals.

The addition of methyl groups (consisting of a carbon atom bound to three hydrogen atoms) to the DNA is a particularly good indication of age, as many prominent physiological signs, such as tooth development, appear to occur in parallel with methyl rates in various types. By comparing methyl levels in the Labrador dog breed, for example, on the one hand, and humans, on the other hand, researchers have come up with a formula by which to map the dog's age and compare it with the age of humans.

That formula, or equation, is indicated as follows: the corresponding lifespan of humans = 16 (dog's chronological age) + 31. (The) here represents a mathematical parameter known as the natural logarithm, which is known in the irregular calculations of the energy released by Earth in earthquakes (Expressed on the Richter scale) or for sound measurement (in decibels). And logarithmic calculation may help explain why we feel that life is getting faster with us.

The study indicates that the dog reaches a steady speed in the beginning and then slowly grows old, meaning that most of his life is spent in the middle stage of life.

For convenience, we say that the first year of a dog equals 31 human years, and then after that, the dog's time life doubles, the corresponding increase in human years increases by 11. Thus, eight years represent three "multiples" (one to two years, two to four, and four to eight - three times), which gives the dog a corresponding 64 years of human life.

Dog lovers must have realized that the interview between a dog’s age and a person’s age doesn’t go in a regular way, as they notice that their dogs reach a lot faster than they assume according to the linear parameter one to seven.

An adjustment was made to one factor to seven, to suggest that each of the first two years of the dog corresponds to 12 human years, while the subsequent years are counted against four of the human years.

In practice new discoveries of molecules related to meeting a dog's lifespan for humans - formulated by the aforementioned logarithmic base - indicate that dogs are of a much faster lifespan than most owners think. Therefore, when you notice that your dog is no longer concerned with chasing the ball as before, perhaps because he grew up and passed the stage and did not return as he was familiar with it!
