Calculating dog years to human years is a fun and easy calculation to make using your dog’s age. Our dog years calculator has been designed exactly for this purpose. To use this calculator, simply input how old your dog is and the calculator will output your dog’s age in human years.

While people have been trying to convert dog years to human years for ages, there are several myths and incorrect formulas that are often used and can result in false information. The most common inaccuracy and incorrect belief when calculating dog age to human age is that you simply multiply the dog age by a factor of 7. This assumes that every year in a dog’s life is equivalent to 7 years in a human life. While not completely far off, this is a myth because all dogs age and mature much quicker in their first initial two years of life compared to any later years.

According to most canine experts, the first two years of a dog’s life are roughly equivalent to 10 ½ human years. Each additional year of life beyond the first two years can be calculated at 4 human years. For example, let’s say you are calculating the age of your dog that is five years old. This dog would be the equivalent of 33 human years old (10 ½ years + 10 ½ years + 4 years + 4 years + 4 years). This is the formula that we use in our dog age calculator and it’s the formula that we believe is the most accurate for this calculation.
