The idea that dogs age seven years for every human year is a myth, scientists have claimed.

University of California researchers said they have also found puppies are middle-aged by the time they are two, although dogs tend to age more slowly than humans in later life.

By the time they get to three – and are possibly still getting away with things due to being considered young – dogs are closer in age to a 50-year-old human, according to the university’s research.

The study looked at how dogs aged by focusing on the DNA methylation in 104 Labradors aged between four weeks and 16 years.

Fanged mouse-deer identified after vanishing for a generation

  Fanged mouse-deer identified after vanishing for a generation A small group of silver-backed chevrotains, tiny deer-like creatures, has been photographed in a Vietnamese forest after an intense search.Lost to the outside world for a generation—and feared extinct—a small deer-like species with tiny fangs has been photographed tiptoeing through a dry lowland forest in southern Vietnam. The last known scientific recording of the animal, known as the silver-backed chevrotain (Tragulus versicolor), dates to 1990, when a hunter killed one and donated the specimen to scientists.

One year for a dog is often said to be equivalent to around seven human years , but new research has suggested they are closer to a 50- year -old human by the age of three. The DNA contains marks which change over time as a cell matures, allowing scientists to track the biological age of a species.

After assessing the results, the researchers compared their findings to those from 300 humans.

By the age of two, the Labrador DNA was equivalent to a human in their early 40s, rather than the 14-year-old, which the traditional formula would suggest.

However, ageing slows in dogs over time, meaning that by the age of 10, a Labrador is similar to a person aged 68.

This ties in with the long-held formula for calculating the age of dogs, which was developed on the assumption that most canines lived until around 10, while humans lived until around 70.

“The expected lifespan of Labrador retrievers, 12 years, correctly translated to the worldwide lifetime expectancy of humans, 70 years,” the researchers said.

But if anyone thinks this research makes puppies any less lovable, the scientists also observed similarities in the ageing process whereby eight-week-old puppies resembled nine-month-old babies.
