Dog Years To Human Years

Dog Years To Human Years

Dog owners always care about their dogs’ age, and many of them try to calculate dog years to human years. In this article, dog owners will be able to know many things about their dogs’ age depending on some real facts. On average, humans live dog’s age × 7. That means that when a dog lives one year, it equals a 7-year-old human person. However, this calculation is not accurately right as some humans die before they reach 70 of age, or even, some of them stay alive 100 years! The same thing is applied in dogs as some dogs live up to 20 years, and some of them die when they are still puppies.

How To Calculate A Dog’s Age Easily?

According to an assumption that states that dogs stay alive till ten years and humans live to about seventy, you can calculate your dog’s age by simply by taking one dog year and multiple it by seven.

For an instant, a dog that is 3 years old is 21 “human years.” Actually, this way is a good one that makes us always remember that our dogs do not like our children. It is good to keep in mind that, from a health perspective, as dogs get older, they absolutely need extra attention and care.

Large dogs become seniors at the age of five to six, while small breeds generally become seniors at the age of 7. All dog owners should visit the vet periodically to avoid many diseases such as hearing and sight issues, weight control, irritability, discomfort, and arthritis. Many changes in activity or behavior can lead to more serious issues, shorter and unhealthy life.


The More Accurate Calculation of Dog Years

In fact, many sources have been helped to learn more about how dogs age, such as veterinary hospitals, breed-club surveys, and Statistics from pet-insurance companies.

To be honest, it is not correct that dogs age at a rate of seven human years for each year in dog years.

The actual calculation of dog years to human years is that every dog year equals approximately 4-5 of a humane year. But that does not apply to the second and the first years, as the second dog’s year equals 9 humane years. Whereas, the first year in a dog’s life equals approximately fifteen years in a human’s life, according to the American Veterinary Medical Association.
