Smaller dogs generally live longer than larger dogs. Some of the longest living dogs have been known to live upwards of 20, even 25 years. To put that in paws-pective, 20 years old for a dog equates to 140 years old in dog years, which is an incredibly long lifespan.
The average lifespan for medium-sized dog breeds is 10 to 13 years, with some breeds living even longer. As with small dogs, exact age ranges for medium-sized dog breeds are hard to determine, but there are general lifespan guidelines for each breed.
The aging profile of dogs varies according to their adult size (often determined by their breed): smaller dogs often live over 15–16 years, medium and large size dogs typically 10 to 13 years, and some giant dog breeds such as mastiffs, often only 7 to 8 years.
Although most people think that one human year of age equals seven dog years, it's not that simple. ... Small breeds are considered senior dogs around 10-12 years old.

Lifespan in general is determined by trade-offs between survival and reproduction. Wolves, the ancestors of dogs, can live 15-20 years, roughly twice as long as comparable-sized dogs. They start breeding in the wild no younger than 2 years old. They need to form pairs and establish a territory before breeding.

The findings suggest that gender has no effect on the cause of death and a small effect on longevity — males live slightly longer. The majority of differences in canine longevity seem to be due to the effects of spaying and neutering.
The larger the dog, the shorter their life expectancy. ... A large dog like a Saint Bernard will have a lifespan of between five to eight years, while smaller breeds can generally live as long as 12 to 15 years.

Obviously, his stronger sense of smell is useful, but it's also because dogs can see movement and light in the dark, and other low-light situations, better than humans.
