What I do is feed straight up raw and I mix it up a bit day to day......in that basic meal lets say chicken day,I add in yogurt,1egg soft boiled,some organ meat and to make sure they get a balanced meal I supplement with Natures Variety Instinct Raw.No matter the day I throw a little of that in there....Seems to work.The Vet is shocked at my dogs "look" and the results.
