To me, they're both GREAT kibbles. And Acana Provincals is their grain-free line which includes Grasslands, Prairie Harvest and Pacifica. They don't offer their non-grain free lines here in the US. I feed Grasslands and Jackson loves it! We've been feeding it since March or so and he still seems to really enjoy it. I do mix some wet food as well. But he usually has firm small poopies and goes about 2 times a day, sometimes 3 if he had extra treats or bully sticks, etc. I highly recommend either of the foods, Champion Pet Foods is the best out there, IMO.
