The first year of a dog’s life is equal to 15 human years.
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.
To calculate a dog’s age to human years, you can use this formula created by researchers: (human_age = 16ln(dog_age) + 31).
This formula is pretty complex.
For an easier way to estimate your dog’s age, you can follow a chart for small, medium, and large dogs under 100 lbs.
Generally, you can group dogs into four different categories: small dogs (under 20 lbs), medium dogs (20 to 50 lbs), large dogs (50-100 lbs), and giant dogs (100+ lbs).
Use this chart to calculate your pet’s age in human years.
To find how much is 1 second in dog time, we must first find how much is 1 year in dog time in human years, and we know the first year of a dog’s life is equal to 15 human years.
Since 1 year has 31,536,000 seconds, then 1 second would be equal to 31,536,000 / 15.
