Here's how we calculate that:
* First 2 years: The first two years of a Yorkie's life are equal to 10.5 human years each.
* Following years: Each year after that is equivalent to about 4 human years.
So, the calculation would be:
* (2 years * 10.5 human years/year) + (12 years * 4 human years/year) = 98 human years
Keep in mind, this is just an approximation. The actual age in human years can vary slightly depending on the individual dog's size, breed, and health.
