Unsolicited paranoia?

It arrived in the mail. Unrequested; unsolicited.

A 7 x 10 envelope screaming THE DOG FOOD BLACKLIST… If you are feeding any of these to your dog—Stop Now and Reconsider! (SEE OTHER SIDE)

Okay. So we turn the envelope over to read:

Warning: Feeding THESE dog foods to your dog could be hazardous to his health!
The canine equivalent of Twinkies (Product named Inside)
The toxic dog chew (Product named inside)
The “real beef” food that’s a real turkey (Product named inside)
The “top dog” of misleading advertising (Product named inside)

INSIDE: Get a FREE COPY of the Special Report many dog food manufacturers hope you’ll never see!
Ordinarily, we are quickly turned-off by so many exclamations and dire bold-face warnings and toss the fear-invoking missive into the trash. But, since it was about dogs, we thought, why not take a look. More to come.
