HOW OLD IS MY DOG?

How Old Is My Dog?

It is often said that people live 7 times as long as dogs so each year of a dogs life is equal to 7 years of a humans life. That's a bunch of hooey and here's why:

The longest living dog breeds have an average lifespan which is double that of the shortest living dog breeds. So to determine your dogs age you need to take into consideration the breed and other factors.

Most breeds (especially the smaller breeds) have a relatively short childhood compare to people. A small dog with an expected lifespan of 15 years would be mature (sexually and physically) within 1 year. A man with an expected lifespan of 75 years would have the equivalent maturity at 15 years of age. Thus the dog reached maturity in 1/15th of its lifespan whereas the person was mature in 1/5th (15 years / 75 years) of his lifespan. Soooo, while one can say that the man is living 5 times as long as the dog, so each dog year is equal to 5 human years, the first year of life for the dog sees the same amount of development as in the first 15 or so human years. For this reason, an accurate mapping of dog years to human years needs to consider factors other than expected lifespan. The following table does this, considering the different development stages and the rates at which they are reached (on average) for the different sizes of dogs. 

So, it looks like on my next birthday (April 10th, get those gifts in the mail quick!) I will be 65 and eligible for Social Security.  Hmmm... I wonder if I should join AARP??

No matter how old you dog is, he has no idea of how old he is.  Age, time and space has no meaning for a dog.  All that matters is the HERE and NOW.  Respect that. Nurture that.  Not only will you learn somthing about your dog, but also something about yourself!  There is no past, there is no future, only the HERE AND NOW!!
