How Old Am I?

Calculate Your Age in Dog Years or Your Dog's Age in Human Years!

Dogs live shorter lives and consequently age faster than we humans do: use our calculators to compare dog and people ages!

Previously it was believed that seven dog years were equal to one of our years. New research has proved this to be inaccurate, and that young dogs mature faster than young children and teenagers. In addition, different breeds have differing life spans which are related to their size, and this is also factored into the age comparisons.
