Both of our dogs are on a natural/raw diet, thankfully, so none of this has had an effect on them.  I truly feel for those who've lost their companions (or had close calls) due to this issue.

I highly recommend natural/raw diets for both dogs and cats...  It's worth looking into, for those who haven't considered the approach.  While it takes a little more effort (primarily to educate one's self on the topic), I have found it has made a world of difference in their overall health, vitality and well-being.  (And we know what they're eating -- there are no worries about mystery ingredients or tainted content!)
