Dogs grow steadily in their first year until they grow up to 31 years of human life

Anyone whose dog is ten years old knows that the lifespan of this animal can be equal to the lifespan of a human who has lived for more than 70 years, calculating that each year of a dog’s life is equal to seven years of human life. which is the calculation that has been achieved taking into account that the average life expectancy of humans is 77 years, while the average lifespan of a dog is about 11 years.

However, new research reveals that things are not so simple, and seeing some of the obvious signs of growth, it becomes clear why. For example, most dog breeds reach sexual maturity between the ages of six months and one year – and by Taking the maximum and meeting it with the traditional method of calculation, puberty will correspond to seven years in humans. Moreover, the lifespan of dogs can sometimes be extended, if rarely, up to 20 years, and if we apply the rule from one to seven, this will correspond to 140 years in humans, which is unrealistic.

The average lifespan of a dog depends largely on its breed. Smaller dogs usually have a longer lifespan, which means that they age more slowly than larger dogs.

All of this raises the question of what is meant specifically by age. Perhaps the direct method of calculating age is the number of years since birth, which is called the chronological determination of age. However, there are other definitions of age, such as biological age; It is a subjective definition based on the assessment of physiological indicators to monitor an individual’s growth and development, including measurements such as the “weakness index” – which takes into account the individual’s health status, degree of impairment, cognitive ability and level of activity.
