The idea that one dog year equals seven human years is a common misconception. While it is true that dogs age faster than humans, the rate at which they age varies depending on factors such as breed and size. Moreover, the way dogs think and perceive the world is not directly correlated with their age in human years.

That being said, researchers have attempted to estimate how dogs perceive time and process information based on their developmental stages and cognitive abilities. It is believed that by the age of 6 months, dogs have reached the equivalent of a 10-year-old human child in terms of cognitive development, with the ability to learn basic commands and understand human gestures and facial expressions.

By the age of 2 years old, dogs are believed to have reached their full cognitive development and are capable of problem-solving and reasoning at a similar level to a 2 to 3-year-old human child. However, it’s important to remember that dogs have their own unique way of perceiving the world, and comparing their cognitive abilities to humans is not an exact science.
