Dog life expectancy calculator
Everything you need to know about the lifespan of a dog
Dog ownership brings endless joy to people’s everyday lives. Nonetheless, dog owners must face the unfortunate inevitable, that people live much longer than their furry companions. On average, dogs have a lifespan of 10 to 13 years at best.
Obviously, this age number, is not necessarily true for every breed, for the reason that there is a wide variety of life expectancy between the breeds, depending on their general health and their sizes.
It is commonly believed that smaller breeds tend to live longer. This is backed by the theory that larger dogs show the signs of aging, and also tend to grow up faster.
This rapid development in the early days of their lives can lead to an earlier occurrence of abnormal tissue developments, like cancerous tumors and aging-associated illnesses including arthritis.
Mixed or purebred
Another differentiating factor in dog life expectancy is being purebred, or a mixed “mutt”. It is proven to be true, that purebreds who were massively interbred can be subject to more health problems, due to the interbreeding and their genetic makeup.
Moreover, inbred dogs can carry specific genes for a particular disorder for multiple generations. Meanwhile, mixed dogs who have at least two breeds tend to have the least health problems and live longer than anticipated.
Even though the dogs’ disease is unavoidable, the owner can significantly increase his / her companion’s life expectancy. Usually, a dog with a proper, nutritious diet and regular exercise can live a longer, happier life than one without these.
In addition, taking the dog to the veterinarian for regular wellness exams and getting the dog booster shots, can also benefit the dog in the longer run.
Moreover, taking precautions, and having the dog checked up regularly also can result in finding the possible health problems and illnesses at an early stage, where they can possibly be treatable.
Neutering and spaying a puppy relatively early on, can also positively affect the dog’s lifespan. Multiple scientific studies show that these surgeries can help decrease the risks for some types of cancer affecting the breasts, testicles, and ovaries.
Other studies have suggested that in the case of female dogs, their life might be easier, and can also benefit from not having a litter of puppies, however, this theory has not been proven yet.
A better way to understand the dogs’ lifespan is to convert their “dog years” into “human years”. There have been multiple studies around this question because it is a well-known fact that puppies tend to grow up faster and reach the age of fertility earlier than humans.
The most widespread theory is that one dog year equals 7 human years, however, this calculation method had just been recently falsified.
A new study, published in 2019, based on the changes in the dogs’ DNA over time suggests that the dogs’ first year equals 15 human years the second year equals about 9 human years, and after that, every year can account for about 5 human years.
However, this calculation method can vary from size to size. You can easily find out with our dog life expectancy calculator.
