How old is a dog in human years? Scientists have found the exact way to calculate

For years, it was dog owners They used the rule that one animal year equals seven human years for their calculation age of their pets in human years. However, a new formula developed by scientists showed that the way we calculated the age of dogs was far from accurate.

The formula, developed by researchers at the University of California, San Diego, takes into account changes inDNA methylation patterns that occur as dogs age, providing a more accurate estimate of a dog’s age in human years.

The study, published in the scientific journal Cell Systems, analyzed DNA methylation by 104 Labrador Retrievers They range in age from a few weeks to 16 years, allowing the researchers to create a new formula that more accurately determines how old a dog is to its human counterpart.

From one to seven years: “An overly simplistic rule can lead to misunderstandings”

As it turns out, a 1-year-old dog is the equivalent of a 30-year-old human, while a 4-year-old dog is the equivalent of a 52-year-old human. This new formula suggests just that Dogs grow quickly in the first two yearswith a 2-year-old dog meeting a 42-year-old human.

the traditional theory thatOne dog year equals seven human yearsIt is based on the average lifespan of the dog and human rather than any specific biological process. However, the new formula is based on changes in DNA methylation patterns that occur as dogs get older.

According to lead author Trey Ideker, PhD, professor at UC San Diego School of Medicine and Morris Cancer Center, “the new system is superior to the previous ‘multiplication by seven’ system,” Overly simplistic judgment which could lead to wrong concepts About how dogs age.

The new formula could matter Benefits in veterinary care, providing a more accurate way to determine a dog’s age-related health risks. In addition, it can also help veterinarians determine the best time to perform certain medical procedures, such as neutering, which may have different risks and benefits depending on the dog’s age.

It is also important to her Understanding the aging process in dogs, which may have implications for human aging research. As dogs age, they experience many of the same physical changes that humans do, including changes to the immune system and an increased risk of diseases such as cancer.

By then, the aging of dogs had slowed down, so one 8 year old dog looks like one 64 years old.

The new formula

the equation: 16 years (dog age) + 31 = human age

for calculators iPhone Which has the natural logarithm or “In” function, enter the dog’s age first. Then press the ln button. Multiply this result by 16, then add 31.

If you use its scientific calculator Google: First press the “ln” key, then enter the dog’s age, then set it. Then multiply by 16 and then add 31.

Using this equation:

• A 1 year old dog is like a 31 year old human,
• A 3-year-old dog is like a 49-year-old man,
• A 7-year-old dog looks like a 62-year-old man.

The new method of calculating a dog’s age in human years has both dog owners and veterinarians excited, though many are concerned, noting that It may not apply to all dog breedsbecause they have a different age and may vary in age.

Nevertheless, it is an important step in understanding canine aging and health and provides a more accurate and evidence-based approach to estimating its lifespan in human years.
