Recently announced - recalls on dog foods http://www.petcare.mars.com/ They are recalling certain brands in which the first two numbers of the UPC are 17. I have put in a call to our FDA office in Michigan, because I have food not of the listed brand, but with the indicated UPC - - - AND my dog has had mystery tummy aches a couple of times in the past month. I have spoken with my vet & she has shrugged it off. "He's a puppy; he eats weird things, like bark; he's gonna get a tummy ache..." What I am curious about is whether these UPC codes indicate the manufacturing plant of origin? The other suspect in the pup's tummy troubles are Pig Ears. Has anyone else had issues with these?
