How Old Is My Dog in Human Years? Dog age calculator by Breed & Size

Understanding dog years vs. human years isn’t as simple as “multiply by seven.” Dogs age at different rates depending on size, breed, and lifestyle.

• Small dogs often live longer and age more slowly after maturity.

• Large dogs grow slower at first but age faster in later years

• This means a Chihuahua could still be spry at age 12, while a Great Dane might be a senior by 6.
