It was confirmed they changed their formula and added soybean oil to a few formulas (Charlie is allergic and makes him ITCHY!!!) so I switched to Canidae.

What really IRRITATES!!!!!!!!! me is the fact that they do not even announce these formula changes!! If it weren't for places like PT or dogster forums, I would have never known and poor Charlie would have had to suffer until I found otu what caused the problem.
