Your Dog is Older Than You Think

A recent scientific study has debunked the traditional belief that a dog's age compared to human aging may be calculated by multiples of 7 (Multiply the dog's age by 7 to calculate the age in human years.)

104 puppies, just weeks old, were observed and tested daily for 16 years. It was discovered that methilaton chemical marks on a dog's DNA cause a dog to age more rapidly during its first 5 years, then more slowly thereafter.

A 1-year-old dog is 30 years old in human years.
A 3-year-old dog is 49 years old in human years.
A 5-year-old dog is 60 years old in human years.
A 7-year-old dog is 62 years old in human years.
An 8-year-old dog is 64 years old in human years.
A 12-year-old dog is 70 years old in human years.

The aging process varies slightly depending upon the size and breed. However, the comparisons listed above serve as a valid general guideline.
