Practical Example Calculation

Scenario Context: 5-year-old medium-sized dog converting to human years.

Step 1: Year 1 = 15 human years.
Step 2: Year 2 = +9 human years (total 24).
Step 3: Years 3-5 = +5 human years each (+15 years).
Step 4: Total = 24 + 15 = 39 human years.
A 5-year-old medium dog is roughly 39 human years old.
