I'd better confess straight away that although I mostly 'raw feed' Penny, she does get commercial dog foods some of the time. For instance, I like Nature's Gift canned food and Ziwi canned foods when I am looking for something to stuff into her kongs and freeze. This is especially useful in the hot weather we're having.
I also feed Eagle Pack and Evo dried food on occasion, often in some sort of interactive toy where she has to work to get the food out.
I also use 4-Legs cooked food and their meat treats.
Today I was reading Bark Blog and followed a link to The Dog Food Project by Sabine Contreras, where there is list of ingredients you might find in commercial foods. The author says it will be updated as more information becomes available. To me it seems a useful reference. When I'm thinking about buying new food I could check it against this list. I think I might get out some of the foods on our shelf and check the ingredients.
