I agree! Why they do it is beyond me but, I know dog food companies aren't the only ones doing it.I hate the lack of transparency with the companies as to who is really making their foods. I have read of some general discourses amongst some people about Blue Buffalo being bought out by.. General Mills, I believe? So far I have had no problems, knock on wood.
I have heard good things about Earthborn. I think I tried some of their cat food years ago and my picky eater did not like it but maybe I will try it again, lol.
I have come to a conclusion that any company can simply lie. It's a bit off the topic of dogs but an example, when companies can claim they're Non-GMO only to find out later they really are GMOed.
