How old os a 9 yeard kid in dog years?

Dogs age at a different rate than humans, so calculating a 9 year old kid's age in dog years is not straightforward. However, one common rule of thumb is that you can multiply the child's age by 7 to get an approximate equivalent in dog years. This is because dogs are considered to be adults by the time they are 2 years old, and the following years roughly correspond to 5 human years. Using this calculation, a 9 year old kid would be approximately 63 years old in dog years.
