Introduction to Fox Terrier Age to Human Age
A long long long time ago, people thought that one year in a dog`s life was equal to 9 human years. Evidence of this could be found on a 1268 inscription on the floor of Westminister Abby stated that .
Then a long time ago, one year in a dog`s life was thought to be equivalent to 7 human years. However, you do not need any knowledge of science to know that this conversion does not make sense.
To debunk this 1 dog-year-to-7-human-years myth, take a 1-year-old Fox Terrier as an example. A one-year-old Fox Terrier is mature enough to make puppies. However, a seven-year-old human is no where close to being capable of having babies.
The moral of this is that aging in Fox Terriers, as well as in humans, does not follow a `straight line`. In scientific terms, aging is not linear. So, you cannot just convert your Fox Terrier`s age to its equivalent human age by just multiplying by a single number.
Therefore, in 1953, a French researcher by the name A. Lebeau published a paper to show that the relationship between a dog`s age and a human`s age is not constant over the lifespan of the dog. Lebeau`s paper is titled “L`age du Chien et celui de l`Homme. Essai de statistique sur la mortalite canine“ (The age of the Dog and that of the Man. Canine Mortality Statistical Essay).
Also scientists have shown that, one size may not fit all when it comes to converting a dog`s age to its equivalent human age. Small-sized dog breeds live longer than giant-sized dog breeds. Hence, smaller dog breeds age slower than giant breeds.
Therefore, in 1997, researchers from Purdue University developed a dog age to human age conversion method that extended Lebeau`s work. Their method also took breed size into account in converting a dog`s age to its human age equivalent.
Here, we have developed a dog-age-to-human-age calculator and table that lets you convert your Fox Terrier`s age to its human age based on the method developed by Purdue University veterinarians.
Also, recently in 2020, researchers from the University of California, San Diego (UCSD) developed what they called “a better method” for converting a dog`s age to its human age.
Here, we have also developed a table and a calculator that lets you convert your Fox Terrier`s age to its human age based on the method developed by the scientists from UCSD.
The scientist at UCSD compared the DNAs of humans and the DNAs of dogs at different ages to develop a mathematical relationship between dog age and human age.
Finally, we developed our method and its calculator that lets your convert your human age to your Fox Terrier`s age. You are definitely not as ‘old’ as you think (in Fox Terrier`s years).
In summary, this article contains:

How to Convert Your Fox Terrier`s Age to Human Age
In 1997, researchers from Purdue University developed a method for converting a dog`s age to its human age. Their method was based on the 1953 work of the French Veterinarian, A. Lebeau.
To convert a dog`s age to its human age, Lebeau divided the stages of a dog`s life roughly into puberty, adulthood, old age, and end of life. He then proposed a series of numbers that can be used to multiply a dog at each of these different life stages to obtain the dog`s equivalent human age. That is a multiplier for converting a dog`s age at puberty to its equivalent human age, another different multiplier for converting a dog`s age at adulthood to its human age, and so on.
Researchers from Purdue University took Lebeau`s work further by taking into account two important factors to develop a more accurate method for converting a dog`s age into its human equivalent age:
- The size of a dog`s breed: Smaller dog breeds live longer than larger breed dogs
- Lifespan of a dog`s breed: Dogs that live longer lives will age slower than dog`s that live shorter lives
The average lifespan of the Fox Terrier is 13.1 years.
Fox Terrier are small-sized dogs. Fox Terriers weigh 15 pounds to 19 pounds.
The method developed by the Purdue University veterinarian researchers took into account the lifespan and size of Fox Terrier in converting Fox Terrier age to human age.
The researchers used 5,608 mixed breed dogs and 17,927 purebred dogs to develop the method for converting the ages of dogs (of different breed sizes and lifespans ) to their equivalent human ages.
The calculator below lets you convert your Fox Terrier`s age to its human age. Just enter your Fox Terrier`s age in the calculator and it will compute your Fox Terrier`s human age. If you do not know your Fox Terrier`s exact age, enter an approximate age in the calculator.
Also, the table below shows how old Fox Terrier is in human years based on the method developed by the researchers.
Note that your Fox Terrier`s human age changes day by day. Therefore, always check back to use the calculator to find your Fox Terrier`s up-to-date human age.

Your Fox Terrier`s Age to Human Age (New Method)
The new method created in 2020 by the University of San Diego researchers for converting a dog`s age to its human age is based on what is called “epigenetics”. Epigenetics is the study of “how the way an animal lives changes the animal`s DNA”.
Thus, with epigenetics, one can learn about a person`s life or a dog`s life simply by ‘scrolling’ through the DNA of the dog or the human (take that Instagram!).
With the techniques of epigenetics, scientists can look at a man`s, a dog`s, or a mouse`s DNA to figure out how old the man, the dog, or the mouse is, without anyone telling the scientist when the man, dog, or mouse was born. This is pretty cool.
This is kind of similar to counting the teeth of a horse to determine the age of a horse or counting the rings in a tree to determine the age of the tree, etc. However, the techniques used in epigenetics are way more accurate than crude methods of estimating age by counting teeth or rings. This is because the methods of epigenetics looks at the DNA.
Furthermore, one can match the signatures of aging seen in a dog`s DNA to the signature of aging seen in a human`s DNA to convert a dog`s age to its equivalent human age.
According to the researchers, converting a dog age to human age makes sense because dogs (especially Fox Terriers) and humans live together and share similar lifestyles. Our Fox Terriers are exposed to the same environment as we do. We treat our Fox Terriers as we treat ourselves.
We take our Fox Terriers to the animal doctors just as we humans take ourselves to doctors for health checkups or treatment when sick. We give our Fox Terriers vaccines and medications, human-style. In short, Fox Terriers have similar lifestyles as humans do. Therefore, a dog`s life and human life will definitely mirror each other.
No other animal species has such an intimate relationship with humans as dogs do. Dogs and humans have come a long way together.
Furthermore, dogs and humans go through similar well-defined life stages: birth, baby stage, young age stage, adolescence, adulthood, and old age. Therefore, converting a dog`s age to a human age is not a wild idea.
Based on their study of 104 Labrador Retrievers, the UCSD researchers came up with a neat formula for converting dog age to human age. Interestingly, this formula applies to aging in mice as well, and the researcher believes that the formula will apply to all dog breeds, and just not the Labrador dog breed that they used in their study.
The formula they came up with is:
human_age = 16 ln(dog_age) + 31
Use the calculator or table below to convert your Fox Terrier`s age to its human age based on this formula. For the calculator, simply enter your Fox Terrier age in the calculator to get its human age and its human birthday.
