How Old Are You in Dog Years?

Comparing Human and Dog Ages

Most dog owners know that humans age slower than dogs. The general rule is that one year in your dog's life is equal to seven years in your life. However, the math isn't quite that simple. Dogs age quickly in their early years, and then their rate of aging slows. Additionally, different breeds and the size of your dog affect their aging process. Smaller dogs age more slowly than larger dogs. Look at this chart for a 5-year-old dog, 10-year-old dog, and 15-year-old dog to see the comparisons.

Use this calculator just for fun to see how old you are in dog years. It will be different from the chart as it uses the rate of dogs aging seven times faster than humans.
