Dog age vs human age

The old rule that one dog year equals seven human years is not true. New research has indicated that dogs are much older than we think. Based on DNA chemical markers called methylation marks, researchers have been able to come up with a better idea of the age comparison between dogs and humans.

Dogs age faster when they are young and slower as they get older. The article points out that a 6 – 9-month-old puppy is capable getting pregnant which would be the same as a human who has reached puberty. Yet an eight-week-old puppy is equal to a nine-month-old human. A one-year old dog is the same as a 30-year-old human.

The researchers studied Labrador Retrievers and found that a 12-year-old Lab corresponds with a 70-year-old human. The researchers plan to study other breeds to see how their methylation marks relate to corresponding human age. This will be interesting since dog breeds have lifespans from six to eight years up to 16 years. The researchers hope that their findings will help veterinarians determine the best care for different breeds based on their relative age.
