Scientists have discovered that dogs age similarly to humans when it comes to their epigenetic clock, which controls how they age. Researchers studied 104 labrador retrievers of various ages and found areas in the genome where methylation rates were similar to those in humans. This study, published in Cell Systems, provides new insight into dog aging and a formula to calculate their age based on human years.
The study’s findings show that dogs experience DNA methylation, just like humans, and this can reveal information about their age and health. The researchers also developed a new formula to estimate a dog’s age, which is surprisingly complex but has been simplified with the help of a conversion tool.
