Some of the longest living dogs have been known to live upwards of 20, even 25 years. To put that in perspective, 20 years old for a dog equates to 140 years old in dog years, which is an incredibly long lifespan (learn more about how to work out how old your dog is in human years here).
At 30 years and 266 days old, a Portuguese dog named Bobi was crowned the world's oldest dog ever on February 1, breaking an almost century-old record, per Guinness World Records (GWR). The previous titleholder, an Australian cattle dog named Bluey, was born in 1910 and lived for 29 years and 5 months.
Medium-size dogs align more with the overall average dog lifespan of 10-13 years. But some medium-size dogs can be very long-lived; the oldest dog on record was a Rafeiro do Alentejo named Bobi, who's 30 years old and counting! Medium-size dog lifespans and diseases of concern vary from breed to breed.
RESULTS. Men aged 92 to 93 had an overall 6.0% chance of surviving to 100 years, whereas the chance for women was 11.4%. Being able to rise without use of hands increased the chance for men to 11.2% (95% confidence interval (CI) = 7.7–14.7) and for women to 22.0% (95% CI = 18.9–25.1).
Dogs, in fact, have been known to live over the age of 20 (140 human years), and the oldest dog on record was 29 (or 203 human years). The oldest human, on the other hand, managed to stay around until age 122. 2) A 1-year-old dog is more of an adolescent than a 7-year-old human.

The aging profile of dogs varies according to their adult size (often determined by their breed): smaller dogs often live over 15–16 years (no longer than 20 years), medium and large size dogs typically 10 to 20 years, and some giant dog breeds such as mastiffs, often only 7 to 8 years.
As a general guideline, though, the American Veterinary Medical Association breaks it down like this: 15 human years equals the first year of a medium-sized dog's life. Year two for a dog equals about nine years for a human. And after that, each human year would be approximately five years for a dog.
The husky life expectancy is 12-15 years old. They're a healthy breed for their size — most medium to large dogs live closer to 10-12 years.
The “Seven-Year Rule”
Georges Buffon, an 18th-century French naturalist, had more or less the same theory: Humans live to 90 or 100 years, and dogs to 10 or 12.
420 Dog years old, 60 yrs old b-day equivalent in human age.
One of the longest living dogs recorded is an Australian cattle dog named Bluey who lived to be over 29 years old. Then there's the blue merle collie named Bramble who once held the Guinness World Record for being the oldest living dog at the time at 27 years old.
Is 14 years old for a dog? 14 years old can generally be considered old for a dog. A small dog is considered old when they're 11, a medium dog is considered old when they're 10, and a large dog is considered old when they're 8.
Sadly, most mammals technically age faster than humans. This is mostly because other mammals have different DNA to humans, giving them a higher heart rate and metabolic rate. As a result of these genetic differences between humans and dogs, dogs have bodies that go through more wear and tear sooner.
A person who is 10 would be 1.6 years old (or 18 months old) as a dog.
So a 7-year-old dog would be roughly 62.1 human years old.
12 dog years = 77 years. 13 dog years = 82 years.
The first year of a medium-sized dog's life equates to about 15 human years. Year two for a dog equals about nine additional human years, making the dog about 24 in 'dog years'. After age two, each human year adds around five dog years.
The most widely accepted earliest dog remains are those of the Bonn-Oberkassel dog which date to 15,000 YBP. Earlier remains dating back to 30,000 YBP have been described as Paleolithic dogs but their status as dogs or wolves remains debated.
For thousands of years dogs have been our companions and assistants. It's fascinating to see them appear in portraits, next to famous 18th c. figures, or all on their own. They were as beloved and essential to the people of the 18th c.
