The researchers said their new formula doesn't fully address the fact that different breeds of dog age at different speeds. Researcher Trey Ideker said by the time a dog reaches seven years old, its ageing slows. They said a one-year-old dog is similar to a 30-year-old human, while a four-year-old hound is comparable to a 52-year-old person. After a bit of number crunching, they created a graph to show the different rates at which canines and humans age. The researchers analysed blood samples from 105 Labrador retrievers. The scientists regard such DNA analysis as the best way to measure the ageing speed of mammals. It involves a comparison of the genomes of dogs and humans. Their new method requires a little more than simple mental arithmetic to work out a dog's age.
They say it more precisely determines canine age. However, researchers at the University of California San Diego School of Medicine in the USA have come up with a new formula. People have traditionally worked out their dog's age in "human years" by multiplying by seven. For decades, dog lovers have been incorrectly calculating the age of their pet pooches.
