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.
There isn't an absolute scientific formula for determining the average lifespan of a dog, but most pups are cuddly companions for about a decade. According to the Guinness World Book of Records, the longest-living dog ever recorded was Bluey, an Australian cattle dog, who lived nearly 30 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.
Well, dogs are in possession of faster metabolisms and hearts that work harder than our own. Because of all this extra work, dogs age faster and, consequently, live shorter lives. It also means they grow up more quickly. A dog that's a year old is the equivalent of a human child ready to start school.
In 1901, the average human lifespan in the United States was 49 years; today it is 77. Similarly, today's dogs live much longer lives than their century-old ancestors (less than 20% of dogs lived past age six in 1900, as opposed to 44% in 2010).
Scientists have found that although dogs don't live as long as we do, their life expectancy (how long they live) has doubled in the last 40 years. Maybe one day in the future our dogs will live as long as we do. A scientist named Joao Pedro de Magalhaes says that in 1,000 years' time, a dog could live for 300 years.
A rescue pup named Gino is officially the world's oldest living dog, and he lives a life of luxury in California. Guinness World Records declared him the oldest living dog on Nov. 15. He's 22 years and 52 days old, to be precise.
An international team of scientists has just identified what they believe is the world's first known dog, which was a large and toothy canine that lived 31,700 years ago and subsisted on a diet of horse, musk ox and reindeer, according to a new study.
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).
Urfer's study, small dogs had a longer median lifespan at 14.95 years, medium-size dogs lived an average of 13.86 years, and large dogs lived 13.38 years.
Irish Wolfhound: 6-7 years
Originating from Ireland, the Irish Wolfhound is another big dog whose life is cut short due to its massive size. Dilated cardiomyopathy and bone cancer are the leading cause of death and like all deep-chested dogs, gastric torsion (bloat) is common as well.
Licking is a natural and instinctive behaviour to dogs. For them it's a way of grooming, bonding, and expressing themselves. Your dog may lick you to say they love you, to get your attention, to help soothe themselves if they're stressed, to show empathy or because you taste good to them!
According to the American Veterinary Medical Association: The first year of a medium-sized dog's life is equal to approximately 15 years of a human's life. The second year of a dog's life equals about nine years for a human. And after that, every human year equals approximately four or five years for a dog.
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.
It depends. "If the dog has learned to accept kissing on top of the head, then that's fine," says Shojai. "For a new-to-you dog, though, I'd find other more species-appropriate ways to show affection." The truth is that some dogs simply don't like being kissed.
The best way to determine the age of a puppy is by looking at their teeth. All of a puppy's baby teeth should erupt between 3 and 6 weeks of age and their adult teeth should appear between 12 and 16 weeks of age at the front of the mouth and between 16 and 24 weeks toward the back.
Like many animal species, the answer lies in how fast they grow and develop. Dogs grow faster than humans, and therefore, their entire lives are accelerated. Humans, for example, don't start developing teeth until around month 4. Dogs, on the other hand, start teething when they're around 3 or 4 weeks old.
The most challenging time of raising a puppy is the adolescent period. Dogs become “teenagers” and seem to forget everything they have ever been taught. This period is individual to each dog, but it may begin when he's about eight months old and continue until he's two years old.
Most puppies start to calm down as they approach their maturity age, which is usually around 12 months, but for larger breeds it can be more likely to occur between 18 months and 2 years.
The Root of the Behavior
Canines who are aging are likely to grow more affectionate to their human companion as their reliance on them grows.
