how old is your dog really in human

years as researchers come up with a new formula for calculating the true age of

your canine friend and it’s not multiplying it by seven researchers

looked at changes to DNA overtime specifically methyl groups these methyl

group molecules are added to DNA at a consistent rate over time researchers

say this can be used to calculate the age of humans and dogs the Yale team

found a way to match the DNA clock of both species be sure to subscribe and

like our video before we get started calculating the age of a dog in human

years is much more complicated than first thought

scientists claim the idea of the dog’s age in human years is its age times 7 is

a myth according to researchers from the University of California they have

created a new formula for calculating the relative age of a dog compared to a

human based on the rate that molecules are added to DNA the team led by

geneticist Tina Wang say it isn’t easy to come up with a true comparison

between the relative age of a dog and a human as they reach maturity of

different rates and different dog breeds have different lifespans the formula

looks at changes to DNA over time specifically to the methyl groups which

are molecules that add themselves to DNA at a consistent rate they can be used to

measure the age in humans and dogs in a process known as the efficient etic

clock dog lifespans vary from 6 to 7 years for larger breeds to anything up

to 18 years for smaller dogs but despite the lifespan difference they have a

different physiological trajectory they found similarities in the timing of

major milestones between dogs and humans the similarities were particularly

strong when similar aged dogs and humans were compared the new formula based on

the Ephesian etic block involves finding the natural logarithm of a dog’s age

multiplying it by 16 and then adding the to the total using this formula an 18

year old dog would be 77 and a 2 year old dog would 42 in human years

the team did find that there were periods in the life of dogs where the

clocks didn’t match humans including during puberty as they mature earlier in

their lifecycle than humans researchers say even with the issues

around puberty their formula is still more accurate than the dog age plus 7

min this research has been published on bio work so how do you calculate the age

of your dog in human years ISM human age equals 16 LM dog age plus 31 in simpler

terms human age is the same as 16 times the natural logarithm of dog age plus 32

to get to the age of your dog in human years is you multiple the natural

logarithm of your dog real age by 16 then at 31 you can use the Ln button on

a calculator to get the natural logarithm of your dog’s age you can also

use an online tool to calculate the natural logarithm just enter the dog age

to get the correct value you then multiply that figure by 16 and add 31 to

the total example if your dog is 7 then its natural logarithm number will be 1

point 9 4 5 9 you times this by 16 to get to 31 when rounded down then add 31

to find out your seven-year-old dog is 62 in human years you

Thank you for your information regarding the calculation of dog age by humans.

However, I don't think the formula is accurate for every dog.

But, it would be interesting to try calculating my dogs' ages according to the formula.

I gotta try just for fun.
