So it's rather from observations of the ages of dogs that veterinarians have established a correlation table ( age chart) to see an equivalence in human age: Real dog age Indeed, the first year the dog grows five times faster than humans! Like many animals, "childhood" and "adolescence" occur much faster than humans. Practically, there is no mathematical formula (well at least, not a simple one) because the age of a dog does not follow a linear curve compared with the human age. They hope to understand why some dogs develop diseases at younger ages and die earlier, while others lead a mostly disease-free life.Alot people think that to know the "human" age of a dog, you just have to multiply its age by 7, well. It is currently collecting data from pet dogs of citizen scientists to understand how genes, lifestyle, and environment influence aging. Recently, an article in Science about this research mentioned another group that is studying the aging process of dogs, called the Dog Aging Project, a collaborative effort of the University of Washington and Texas A&M University. If you adopted a dog of unknown age, you can determine a dog’s age even if you don’t know their birthday based on physical factors like teeth, eyes, fur, and muscle mass. According to this model, a Miniature Dachshund will age on a 4 to 1 human years scale whereas a Bulldog will age an average of 13 years per human year. In that 2013 study they determined that small dogs age on average 12.5 years per human year, compared to 9 years for large dogs. In a previous study, researchers found a way to calculate a dog’s age, while also taking size and breed into consideration since small dogs tend to live longer. That's a lot of math for pet parents! How to Translate Dog Years To Human Years Your pup’s age must be greater than one year, then that dog age is converted into a natural logarithm and that log is multiplied by 16, and then 31 added for a total.įor example, if a dog is 14 years old, the natural log of 14 is 2.6390, multiplying that by 16 equals 42.224, adding 31 brings it to 73.2. The team also developed a new epigenetic clock and a formula for estimating a dog’s age in human years.

They did find that dogs and humans do have similar age-related methylation of certain genomic regions, especially during aging in both species. infant, juvenile, adolescent, mature, senior.” This translates into a seven-week-old pup equaling that of a nine-month-old child - a time by which deciduous teeth erupt in both pups and babies. The researchers found “that this function showed strong agreement between the approximate times at which dogs and humans experience common physiological milestones during both development and lifetime aging, i.e. This revised approach to determining a dog’s age is based on the actual chemical modifications to a creature’s (human or dog) DNA over a lifetime that create an epigenetic clock - that’s a biochemical test that can be used to measure age. Researchers have come up with a new - potentially more accurate - way to estimate how old your dog is compared to human years. But what is your dog’s age in human years? Turns out, we may have been barking up the wrong proverbial tree with the formula that many of us are familiar with - the simple calculation of one dog year equaling seven human years. Maybe your 15 year old Chihuahua still acts like a teenager or your two year old Great Dane is an old soul.
