Which brand of dog food do you prefer?

So I was checking my account at the electronic high school reunion known to the common man as Facebook, when this survey was thrust upon me as a means to gain advertising revenue.

Which brand of dog food do you prefer?

* Iams * Alpo * Purina * Pedigree



I thought, "How Absurd, I've never, ever ate dog food in my life!?!?" My older sister feed me a box of Milkbones when I was 5, but never dog food. Do you think the advertisers meant to say "Which brand of dog food does YOUR DOG prefer? My black Labrador , Zoe, personally prefers Purina Beneful Playfull Life, but I remain undecided.
