Lifespan Of Dogs
The average lifespan for dogs is between 10 and 13 years. However, the average lifespan varies wildly depending on the breed of dog. While some dogs have an average lifespan of 6 or 7 years some of them regularly live for 15 years or longer.
In general, the smaller the dog the longer the expected lifespan. Oddly enough mixed breed dogs live an average of one year longer than purebred dogs. Because of the huge variance in expected lifespan you should research the lifespan of the exact type of dog you have or plan to own. By knowing what you might expect you will be better prepared to deal with your aging dog as time goes by.
