I was mixing Diamond Naturals with Victor and then with Canine X beef. I think that I am going to stick with Diamond Naturals Chicken and Rice formula. Small amount of stools and dogs look great on it. I also have a couple of days where I feed chicken quarters (mostly on rainy days). Victor just doesn't seem to do the same thing for my dogs as they did in the past. Tried a raw diet but my work schedule (12-hour days) doesn't allow for the proper prep time.
