I was going to post this with a no comment heading originally, except I think it's important to point out that every ad campaign has been marketed to death. Here the folks at Purina have invested some serious time and $$$ into this campaign and have thoroughly researched the demographic they hope to reach with this ad. In other words, it ain't just a stereotype.
Remember, REAL DOGS, like the demographically targeted wiggle butt in the picture, EAT MEAT, and not just lick you to death. And our friends at Purina have the research to back it up.
