Bobi was born on 11 May 1992, making him 31 years old, in human years. He has smashed the record for the oldest living dog, who, until recently, was thought to be 23-year-old Spike, a chihuahua living in Ohio, USA.
Editor's Note, May 16, 2023: On May 11, Bobi turned 31 years old and celebrated at a “big birthday party” with more than 100 guests, according to a statement from Guinness World Records.
30-year-old dog named Bobi is the world's oldest dog ever, Guinness World Records says. (Gray News) – Just two weeks after announcing Spike as the world's oldest living dog, Guinness World Records announced that Bobi, a dog from Portugal, is even older.
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.
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.
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.
So a 7-year-old dog would be roughly 62.1 human years old.
Retired: Our older dogs usually retire from work around 9 to 11 years of age.
Affection, safety and love can work wonders in prolonging your dog's life. Treating your dog like a member of the family will only add to their health and wellbeing.
The first year of a dog's life is equal to 15 human years. The second year of a dog's life is equal to about nine human years. Each additional year is equal to about four or five human years.
However, most sources agree that the Dog Days occur in mid- to late summer. Here at the Old Farmer's Almanac, we consider the Dog Days to be the 40 days beginning July 3 and ending August 11.
If a dog lives to 12 years old, that would equal 84 in human years (if you allow seven human years per one dog year), which sounds fairly reasonable.
According to one tradition, Epimenides of Crete (7th, 6th centuries BC) lived nearly 300 years.
The smaller breeds of dogs tend to live the longest. Yorkshire terriers, Chihuahuas, Dachshunds, Toy Poodles and Lhasa Apsos are the breeds who typically live the longest with these averaging a lifespan of up to 20 years. This is much higher than the average lifespan of a dog which is between 10 and 13 years.
Age is not a disease, and your dog is never “too old” to receive the quality care he or she needs, even if it requires anesthesia and surgery.
Larger dogs that are between the sizes of 50 and 100 pounds are considered middle aged between the ages of 6 and 8. However, dogs that are over 100 pounds in size will be considered middle aged between the ages of 5 and 7.
Current guidelines now conclude the following : 15 human years equals the first year of a small-large sized dog's life. A 2-year-old dog is equivalent to 9 human years. And after that, each human year would be approximately five years for a dog.
This would make a 10-year-old dog 55, 60, 65, or 75, depending on his size. At 14 years they would be 77, 84, 91, and 105 respectively, which seems about right to me.
