Disgusting. Where does this vet get the idea that dogs natural diet is cereal, artificial coloring and flavoring and preservatives? Oh...and a little token of "real" meat? We're not that stupid here to think that carnivorous animals thrive on those ingredients. They barely get by. And if there were tests done, where is the proof? And these tests....that doesn't prove that what caused the deaths was tested for necessarily. They may have tested for certain things, but missed the culprit.
At any rate, as it was said, toxins or no toxins, it's still lousy food, not fit for a carnivore. Too bad they don't just "beef" (pun intened) up their food instead of using their money for the excessive advertising and making cute little shapes and colors. Their reputation is slowly being tarnished with the advent of Internet. They ought to change tactics and keep up with the trend....change their food to resemble the good foods like Canidae, Innova, Chicken Soup, Calif Nat. etc...Instead of slogging through the mud, pushing these empty, so called dog foods, they could be leading the way, revolutionalizing grocery store dog food, having a "new" angle, a "super food." If they're really smart, they'll do something. Nestle doesn't care, I guess. They're the biggest food giant in the world. What's one microscopic little trouble spot?
