The concept of translating a dog's age into human years is familiar, and the conventional wisdom holds that 1 canine year is the equivalent of 7 human years. However, there is no empirical evidence to back up that view. Little dogs tend to live longer than giants of the same breed. To what extent can we convert a dog's age to human years?
How to Convert Dog Years to Human Years
It's a familiar idea to try and extrapolate a dog's age into human years; the conventional wisdom holds that 1 canine year is equivalent to 7 human years. Recent studies, however, have disproven this notion as scientifically valid. In fact, little dogs tend to outlive their larger canine counterparts by a significant margin.
Therefore, what method can we use to determine how old a dog is in human years? A rough formula for translating canine years into human years has been offered by the American Veterinary Medical Association (AVMA). The American Veterinary Medical Association states that a medium-sized dog's first year is roughly equivalent to 15 human years. A dog's second year is roughly equivalent to 9 human years, and each subsequent human year is roughly equivalent to 5 dog years.
If so, I wonder how researchers arrive at such precise estimates. The size differences between humans and dogs are thought to be substantially responsible for the differences in longevity and aging rates between the two species. Generally speaking, smaller dogs outlive their larger canine counterparts. This is likely due to their slower metabolism and decreased risk of developing degenerative diseases as they age.
A study by UC San Diego researchers released in 2019 presented a novel approach for determining a dog's age by tracking the natural evolution of its DNA. This "epigenetic clock" can be used to examine aging in people and dogs by measuring the accumulation of methyl groups on DNA molecules.
Remember that these are only approximations and that a dog's actual age can vary depending on their nutrition, activity routine, and general health.
Methods for Calculating Dog Years
A dog's age can be converted to human years using several techniques. A dog's age in months is often converted to a human age by multiplying the number by 7. The equivalent human age of a dog of two years would be fourteen in dog years, or two times seven or fourteen.
As an alternative, one can refer to the standards set forth by the American Veterinary Medical Association, which state that the first year of a medium-sized dog's life is similar to 15 human years. Dog years are about similar to 5 human years after the first year, which is equivalent to 9 human years. If we use this formula, a dog that is 2 years old would be deemed 24 in human years (15 + 9 = 24).
An "epigenetic clock," which tracks shifts in DNA methylation, is the basis for a more modern approach. University of California, San Diego researchers found that this method may be more accurate than using a dog's chronological age to estimate its human age. However, it still needs to be more generally employed.
Ultimately, it's crucial to remember that various canine breeds mature at varying rates and that little dogs typically outlive their larger counterparts. When converting a dog's age to human years, it's necessary to consider its specific health and way of life.
