I found this today and thought it was interesting since it was posted a couple years ago.  I like information that makes us think about ingredients and their role in your pets food.  Having been in business since 2005 I have seen the rise of grain free and a total shift in the pet food marketplace. As always I believe in a holistic approach to your dogs care so the no soy aspect/legume really had me thinking.  Give it a read see what you think.
