When compared to the average lifespan of a human being, the lifespan of a dog is incredibly short.
This is a terrible truth that comes with owning a dog.
Dogs have a lifespan that ranges from 12 to 15 years on average, but not all dogs are made equal.
There are a variety of diseases that can affect a dog later in life,
and each breed has its own unique genetic makeup.
These diseases can affect a dog in a variety of ways.
The lifespans of larger dog breeds are shorter than those of their smaller counterparts, which is another fact that is also true.
