There are hundreds of anecdotal reports on Itchmo.com of pets sickened and/or dying after eating only dry dog food - even some that doesn't contain wheat gluten. It is impossible to know how many of these reports are accurate, or whether the pets at issue were sickened by some of the recalled treats. However, my own three dogs got very ill after eating only one partial meal from a new bag of dry food I opened about 10 days ago. One of the ingredients listed on the bag is corn gluten. Numerous people have posted on various pet blogs that manufacturers are allowed to substitute wheat gluten for corn gluten and have up to six months to change their labeling. I am still trying to verify the accuracy of this with the manufacturer, but so far I can't get a response about it.
If your pets eat dry food, not on the recall list, and become ill, please notify the FDA, change foods, and take the pets to the vet immediately. As this article indicates, the FDA and the scientists still do not know what toxin is causing the illnesses and deaths.
