Dog age calculator
"One dog year is seven human years" comes from nowhere: somebody divided a dog’s life expectancy by a person’s and it stuck. This uses the Wang et al. (2020) formula, derived by comparing DNA methylation in dogs and in people.
Where this comes from
Wang T. et al. (2020), "Quantitative Translation of Dog-to-Human Aging by Conserved Remodeling of the DNA Methylome", Cell Systems. The formula is human age = 16 · ln(dog age) + 31, derived in Labradors.
This orients you, it does not diagnose. VetSearch is not a veterinary practice. If something looks off in your animal, a vet looks at it.
