There is now scientific evidence to support the observation that smaller dogs live longer than larger ones, as well as a few theories as to why this is the case. This is something that dog enthusiasts have undoubtedly noticed.
“Smaller size, longer life might at first glance appear to be counter-intuitive, especially to families that have gone through short-lived pet rats (2 years), hamsters (3 years), or gerbils,” according to research on the longevity of other animals (4 years).
Elephants and chimpanzees both have lifespans that are equivalent to humans in the non-pet category. Chimpanzees live for roughly 45 years compared to humans’ 70 years. Of course, this is nothing in comparison to a bowhead whale. Current estimations put its maximum lifespan at 200 years and give it a maximum weight of 65 tons and a maximum length of 60 feet.
By this reasoning, a Great Dane should have a longer lifespan than a Chihuahua, however this is not the case. The latter can live up to 18 years, whilst the former only survive on average 6 or 8 years.
As it turns out, whereas larger animal species tend to live longer than smaller ones, this is inverted within species. The following anecdotal example shows that even people are vulnerable to this rule; Wilt Chamberlain, a professional basketball player, was 7’1 tall and passed away at the age of 63. At the age of 93, Jerry Maren, a 4’3″ actor best known for playing one of the Lollipop Kids in the 1939 adaptation of “The Wizard of Oz,” is still active.
Since dogs come in a wider variety of sizes, the effect is even more noticeable in them. The largest dog, a Great Dane named Zeus, was nearly the size of Wilt Chamberlain, reaching 7′ 4 feet in length and weighing 155 pounds, according to the Guinness Book of World Records. A Chihuahua named BooBoo, who measures 4 inches tall and weighs 1.5 pounds, is the tiniest dog alive.
For instance, if we applied that size discrepancy to Chandra Bahadur Dangi, the shortest verified human, he would measure roughly 31′ 5″. Going the other way, with 8′ 11″ Robert Wadlow as the tallest person, the lowest person would be slightly under 6 inches tall using the same size ratio. Wadlow was just 22 years old when he passed away, whereas Chandra, who is 73, is still alive.
Scientists have recently sought to figure out why this is the case. Researchers were able to put a number on it in a study that was directed by Dr. Cornelia Kraus, a research scientist and lecturer at the University of Gttingen in Germany. In this study, researchers reviewed data on age of death in over 56,000 dogs from 74 different breeds. They discovered that a dog’s lifespan shortened by one month for every 4.4 pounds of added body weight.
The scientists already have some theories, but the next stage is to understand why larger dogs live shorter lives. Simply said, larger canines age more quickly and hence pass away earlier. Because they grow more swiftly, they age more quickly. This may cause tumors and other abnormal tissue changes, such as cancer, to appear more frequently. Additionally, it may result in aberrant development and physical problems that have an adverse effect on health.
The American Naturist will soon publish Dr. Kraus’ work, “The size-lifespan trade-off decomposed: Why giant dogs die early.”
When do most huge dogs pass away?
Although larger animals often live longer than smaller ones, being short has advantages in the world of dogs. Reasons why

The fact that larger animals often live longer than smaller ones in the animal kingdom is something that may be understood without necessarily having a working knowledge of evolutionary theory.
A cat lives longer than a goldfish, whereas an elephant lives longer than a mouse. The observation is valid even for small creatures, such as birds, where larger birds often live longer than smaller ones.
While sparrows typically live for three years, cockatoos can live up to 80. However, dogs are unique.
The life expectancy of larger dogs is decreased. Smaller breeds typically have a lifespan of 12 to 15 years, compared to the five to eight years for giant dogs like the Saint Bernard.
“According to him, there is a body of solid theory in evolutionary biology concerning how animals divide their resources among various purposes. This theory is known as “life history theory.”
“Larger species, like elephants, have slower reproduction cycles that last three to four years. However, they live longer. However, a mouse reproduces once every few months. They live quickly yet pass away young. This is how evolution juggles our reproductive system.
According to Professor Elgar, data that maps canine lifespans provide the key to the mystery “the timetable for a species’ aging process.
This illustrates the connection between an individual’s age and its propensity to pass away. Therefore, even though larger species normally outlive smaller species, smaller individuals may outlive larger individuals within a species.
Additionally, this is crucial when it comes to dogs. Since dogs have been domesticated and bred for millennia, their physical sizes can vary by up to 50 times.
According to Professor Elgar, research comparing size and age-related mortality in dogs demonstrates that larger dogs age noticeably more quickly than smaller dogs, which causes them to pass away earlier.
74 dog breeds in North America were the subject of a thorough study “It appears that a strong positive association between size and ageing rate is what drives the trade-off between size and lifetime.
According to Professor Elgar, a larger dog may put more strain on its physiological functions as a result of its size, which causes them to wear down more quickly.
“Modern automobiles typically function well for eight to nine years before wear and tear takes hold and they begin to break down. The rate at which they degrade varies depending on the manufacturer. The same is true with dogs.
A working dog like a kelpie or sheepdog is more likely to die in an accident than a schnoodle whose only job is to look cute in its favorite chair, just as young males between the ages of 18 and 25 are more likely to die by misadventure.
According to Professor Elgar, the general rule is that “Large dogs often live seven to fourteen years on average, while smaller dogs live shorter lives.
Any Great Dane owner will likely confirm that Fido is the true owner of the couch if you ask them.
Do big dogs have young deaths?
The typical Great Dane lives on this planet for around seven years, digging holes and smelling everything. The typical toy poodle will live for about 14 years, which is about double the average longevity. And most dogs retain that distinction. Their lives are shorter the larger they are. This is strange because it’s not always the case that larger animals live shorter lifetimes when comparing size across species. Big animals can have quite lengthy lifetimes. Blue whales can live to 90 years old, but elephants can live for 70 years. Why then do larger canines pass away sooner?
Recent studies indicate that this is due to their quicker aging. A research published in the American Naturalist examined when and why dogs died based on information from the Veterinary Medical DataBase, which included information on over 50,000 dogs of 74 breeds. According to the American Society of Naturalists:
Large dogs age more quickly than little dogs, as if their adult life is moving more quickly than small dogs’. Therefore, a primary explanation for why huge dogs die young is that they mature rapidly.
How long does a huge dog typically live?
Large dog breeds often live between 8 and 12 years. This includes huge breeds like Great Danes, St. Bernards, and Mastiffs as well as large breed dogs like German Shepherds, Golden Retrievers, Labrador Retrievers, Rottweilers, and Doberman Pinschers. Giant breeds often live 8 to 10 years on average, whereas huge dog breeds survive 10 to 12 years.
Why are dogs so short-lived?
People used to believe that large animals live longer due of a phenomenon known as metabolic rates. A metabolic rate is comparable to how much gas a car uses; similarly to creatures with lower metabolic rates, cars that burn up their gas more gradually can drive for longer. Smaller animals typically have faster metabolic rates than larger creatures, which results in shorter lifespans, similar to how rapidly a car’s fuel is consumed.
The issue is that not all animals respond to this. Despite having fast metabolisms, some parrots can live for more than 80 years! Heart rate and metabolic rate are connected, and some parrots have hearts that beat at 600 beats per minute. The average heartbeat is between 70 and 100 beats per minute.
When do dogs typically pass away?
According to a significant study on canine longevity, which took into account both natural and artificial influences impacting life expectancy,
“In dogs dying of natural causes, the average age at death was 12 years and 8 months as opposed to 11 years and 1 month for all breeds and all causes. Only 8% of dogs lived above the age of 15, and 64% of dogs who died of disease or had to be put to sleep because of it. Cancer was responsible for about 16% of deaths, which is twice as many as heart disease. […] Cancer played a comparable role to heart disease in terms of relevance as a cause of mortality among neutered males. […] The findings also reveal breed-specific disparities in lifespan, disease risk, car accidents, and behavioral issues as a reason for euthanasia.” 
Why do some dogs pass on too soon?
According to recent ground-breaking study, dogs who exhibit undesired behaviors including hostility, fleeing, fighting, excessive excitement, or barking are more likely to pass away at a younger age.
Which dog lives the shortest?
According to a recent study, dog breeds with flat faces, including French Bulldogs and Pugs, had the shortest life expectancies.
The Royal Veterinary College reports that because brachycephalic dogs have a higher chance of breathing issues, skin fold infections, and spinal diseases, they don’t live as long. In spite of record-high puppy registrations for flat-faced dogs in 2020, experts are urging people to pause and consider their options before purchasing a dog with a short nose.
Researchers looked at a random sample of 30,563 dogs from 18 breeds and crossbreeds to investigate how life expectancy varied between each pup in order to discover the results. They were able to determine which breeds live the longest and which tragically do not by examining dogs that passed away between 1 January 2016 and 31 July 2020.
The average lifespan of a French Bulldog is only 4.53 years, compared to 7.39 and 7.65 years for English Bulldogs and Pugs, respectively. However, it was shown that Jack Russell Terriers lived the longest (12.72 years). Yorkshire Terriers (12.5 years) and Border Collies came in second and third, respectively (12.1 years).
According to Dr. Dan O’Neil, associate professor of companion animal epidemiology at the Royal Veterinary College and co-author of the study, “dogs have helped so many humans get through loneliness and isolation of the COVID pandemic.” The owners may now anticipate how much longer they will profit from these pets thanks to the new VetCompass Life tables.
