Is Blue any good? Posted In: Dog Health and Nutrition Participant Jacob OnFebruary 8, 2017 at 12:55 AM #600 I hear a lot about Blue dog food but never tried it for my dogs. I have read some online reviews of people having issues with their dogs liking it after being fed standard pet store brand foods like Purina. Anyone ever used it on here?
