Do you really know the age of your puppy? For many years, we have been told 1 dog year equals 7 human years. But according to a new study released in July, 2020, scientists find out a new way to calculate dogs’ ages, which proves the 1:7 ratios to be an inaccurate measure of age. In this article, Happy & Polly will show you this new way to calculate a dog’s ages. Dog Age Research The research was done by scientists of the University of California San Diego (UCSD) School of Medicine. They worked with genome experts to devise a more accurate formula to calculate a dog’s age. This formula is based on the chemical changes in the DNA. To learn more about dogs’ aging process, scientists gathered and analyzed blood samples of 105 Labrador retrievers, with different ages from a few weeks to 16 years old. They sequenced the genomes of the Labradors to tune “DNA methylation”, which is a process that many species undergo as they age....
