Researchers have created a new equation to calculate your dog's age in human years!
The 'dog years' debate has been up for debate for a long while now, with the 'multiply by 7' myth being shut down.
The new equation to find out your pup's age bases itself on chemical changes to its DNA. It's unclear whether molecular changes in the body occur at the same pace for dogs, humans and other mammals. Researchers have had to look at DNA Methylation (an attachment of three hydrogens and one carbon).
In humans, this DNA seems to have an increased rate as we grow older in life. In the past, scientists have used this with blood donors to figure out their age.
In studies made by researchers, they used 100 dogs, mainly Labrador retrievers, to test the Methylation. The ages of these dogs ranged from 1 month old to 16 years old. They then used the results and compared them to human results, from people aged 1 to 103.
Their final results showed that the Methylation advances around the same speed based on the age of the dogs/humans.
They found 8 weeks of a dog's life was equal to about 9 months of a human's life.
They came up with a simple equation from these results: 16 x dog age +31
came up with a simple equation from these results:
16 x dog age +31
There is more than one dog breed, all of which age at different paces, so these results cannot be used universally for all breeds. More studies are most likely going to take place to evaluate the age of a wider variety of breeds.
These findings were reported on Nov.19.
