I've had mine on Arcana Prairy Blend for some time and other then the initial sticker shock, it's great food and goes a long way.
I agree. Love acana brand. Tried orijen but it was too rich. Made him constipated. I have tried other flavors but he likes the 6 fish. Also, you only need to feed like 2/3 of what they recommend on the bag. He also gets leftover steamed carrots and other treats.
