How to Calculate Dog Age
Dog age is converted to human years based on the following criteria:
- Under 1 year of age: Converted by month. 1 month is 1 year, 2 months is 2 years, 3 months is 5 years, 4 months is 6 years, 5 months is 8 years, 6 months is 10 years, 7 months is 11 years, 8 months is 12 years, 9 months is 13 years, 10 months is 14 years, 11 months is 15 years.
- 1 year: The first year of life is equivalent to about 16 years in human years.
- 2 years: The second year of life is equivalent to about 24 years in human years.
- 2 years and beyond: After 2 years, each year is calculated differently depending on the breed of dog:
- Small dogs: 5 years added each year
- Medium dogs: 6 years added each year
- Large dogs: Every year 7 years old added
