This article was actually on the first page of the soon-to-be-exclusively online Seattle PI. While I know that sometimes people have little choice when it comes to keeping their animals outdoors, you can still tell when the animal is cared for. They have proper shelter, a generally clean environment, room to move, perhaps a leash tied to a runner so they don't get tangled when they run, etc.
The dog spotlighted in this article just doesn't seem to fit that "cared for" criteria.
And he is simply one of many.
