Some People

I cut this from an article on MSN about our recent storms. Please read below and see if you can answer my question.

"Dog rescued Gov. Arnold Schwarzenegger said 82,000 Californians were still
without electricity.
Also Friday, crews made a dramatic helicopter rescue of
a dog stranded on a flooded ledge in the Los Angeles River.
Crews first
dangled a life vest and float ring down to the dog. The animal ignored the items
and began sloshing through the current before stopping on another section of the
flooded ledge.
A helicopter then lowered a rescuer, who scooped up the
frightened animal. The chopper transported the dog to safe ground.
It was
not immediately clear how the dog got in the river."

What the heck did they expect the dog to do with the life vest ? It just made me giggle, I mean duh.
