Small dogs do, on average, live longer than large dogs. This is likely due to the differences in metabolic rates - Chihuahua puppies and Great Dane puppies aren't that dissimilar in size when they are born, but a Great Dane may weigh 20 times what a Chihuahua weighs at adult size. Because the Great Dane (or any large breed dog) grows so much faster, they have a faster metabolic rate which means they also tend to develop diseases like organ failure and cancer faster and they die at a younger age.
