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.
The reason for this is still a mystery to the scientific community.
