How your Dog Ages

It has always been commonly believed that each year of a dog's life is equivalent to seven in human years. However, this isn't exactly accurate, since a one-year-old dog can give birth, whereas a seven-year-old child cannot. And how would you explain the world's oldest living dog on record making it to 29? (That would be 203 in human years!) Then, of course, there's your 11-year-old dog that sure seems frisky for 77. That is why veterinarians have determined that 77 is the "new 60" and have come up with a more accurate way to calculate a dog's age in human years
