So as for why I would argue that smaller animals have faster heart beats and faster metabolic rates in general see graph below and this is the source of their shorter lifespans. As an allegory if you drive 100000 miles on a car it will need maintenance much more.
Why Do Dogs Have Such Short Lives. Loss of genetic diversity also shortens lifespans. In a healthy population essentially all individuals have several defective genes but each defective gene is rare in the population as a whole.
While genetics play a role in how long a dog lives the biggest contributor to short lifespan in dogs are diseases and in particular cancer. Source According to. In addition domestic dogs tend to live shorter lives than wolves.

In terms of lifespan at least it seems that the protection afforded by zoos against predators disease and the elements outweighs any social and behavioural problems arising from life in captivity.
