Your dog is developing at a rate equivalent to a human of this age. Remember that dogs mature much faster in their early years, then their aging slows down compared to humans.
Our calculator uses the latest veterinary research to provide a more accurate conversion of dog years to human years. The traditional "1 dog year = 7 human years" is not accurate, as dogs age faster in their first few years of life.
The size of your dog also matters. Small breeds tend to live longer but mature faster in their first few years, while large breeds have shorter lifespans but mature more slowly at first.
