You’ve probably heard this a thousand times: one dog year is equal to seven human years. But is it true though? Can we really claim that your 5-year old Max would have been a 35-year old man if he was a human?
The truth is that we can’t; despite being very popular, the 7-to-1 analogy is just a myth which most probably originated from the fact that humans have an average lifespan of about 7 times longer of that of a dog’s.
Determining a dog’s age is quite complex and it depends on both the size and breed. Simply said, smaller dogs tend to live longer, but they mature more quickly during their first few years. On the other hand, a larger dog ages more slowly at first, but reaches middle age at 5. Tiny breeds reach “senior” age at around age 10 while medium-sized pooches are somewhere in the middle.
