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.
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.
Australian Cattle Dogs
Bluey, an Australian cattle dog, entered the Guinness Book of World Records by living to the ripe old age of 29 years and 5 months, setting the record for oldest dog ever.
KSNF/KODE — At 30 years and 286 days old, a Portuguese dog named “Bobi” was recently crowned the world's oldest dog ever, breaking an almost century-old record.
Retired: Our older dogs usually retire from work around 9 to 11 years of age.
1. Tortoise. If you want a pet for life, a tortoise is one of the best options out there. Many species of tortoise live for over a century, like the Sulcata Tortoise, Leopard Tortoise, or the Egyptian Tortoise––so chances are this critter may even outlive its human owners.
9-centimeter-tall Chihuahua named shortest living dog by Guinness World Records. Pearl, a 2-year-old Chihuaha, has officially been named the world's shortest living dog by Guinness World Records, the organization announced this week.
1. Border collie. According to The Intelligence of Dogs, which ranks 131 dog breeds in terms of their relative intelligence, the border collie is the smartest dog breed known to man.
A 2019 study from the American Animal Hospital Association shows that, on average, mixed breed dogs live longer than their purebred counterparts. Purebred dogs may have shorter lifespans due to inbreeding.
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.
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.
Dogs can live up to 14 years (some even longer) and are considered seniors at age 7. Smaller dogs typically have longer lifespans than larger dogs. Puppies are not a great choice for most seniors because they need to be housebroken and can be destructive, requiring continuous monitoring.
Signs Your Dog is Aging
We know that dog senior status varies according to size and breed. Generally, small dogs are considered senior citizens when they reach 11 years of age, medium-sized dogs at 10 years of age, large breeds at 8 years of age, and giant-breeds at 7.
420 Dog years old, 60 yrs old b-day equivalent in human age.
Using the simple 7:1 ratio, this same 10-year old dog would be the equivalent of a 70-year old human.
For some reason, the ancient text states that the health of an 81-year-old human would be equivalent to that of a 9-year-old dog.
A 16-year-old dog, depending on his size, is roughly the equivalent of an 80- to 123-year-old person. Like elderly humans, your dog is moving more slowly and sleeping more than he did in his spryer years.
Generally speaking, a healthy dog with a short, smooth coat and no skin problems doesn't need to be bathed often. In most cases, dog baths are more for the benefit of their pet parents than for the dogs themselves. Even so, it's a good idea to bathe your pooch at least once every two to three months.
Physical and Mental Development
A 13- to 15-year-old dog, depending on her size and health, is roughly equivalent to a 70- to 115-year-old person. In her elder years, it is harder for your dog to learn new things. In fact, she likely will be resistant to changes in her surroundings and routine.
