This professional dog age calculator provides the an accurate conversion of human years to dog years. Unlike simple "multiply by 7" calculators, our tool accounts for the fact that dogs age differently based on their size category.
How Dog Aging Works
Small dogs (under 20 pounds) age more slowly in their later years, while large and giant breeds age faster. Our calculator includes precise calculations for puppies, adult dogs, senior dogs, and geriatric pets.
