Yes someone posted an article about this a while ago, sick isnt it?!?! Not even just that but road kill and other dead animals are used in foods also. Thats why getting the best you can afford is so important. Raw feeding is good for the dogs thats for sure, I have known a lot of people who have fed that way with great results. You just have to make sure you use all the supplements that are neccesary also. I have ready also that actually the healthiest combination would be raw mixed with some kibble also.
