I think Redpaw is a musher food, if I remember right. It's used by a lot of long-distance mushers so it really is aimed at extremely active dogs.

Lance Mackey uses it (I think is sponsored by) and he's like the man in the mushing world, and I know of some other long-distance mushers who use it as well.

Dogs actually use fat the same way humans use carbs in terms of energy, but I think in terms of musher's foods you often see carbs as well as fats and protein b/c it is another way of getting energy quickly (and cost-effectively) into dogs putting out a tremendous amount of energy.

Personally I prefer grain-free. I have a very active German Shepherd (runs 40k+ and hikes 60k+ in a day) and I feed him grain-free raw. I am not feeding an entire kennel of dogs though and trying to find storage space for the raw for the number of dogs mushing kennels can contain.

Which I guess is my way of saying that even if you plan on being tremendously active with your dog, for people keeping a smaller number of dogs, such as yourself, there are other options that you might want to look at - if you want to go kibble and not raw, Orijen is a good one and is grain-free.

So the beet pulp doesnt digest or something, and clogs up the pipes maybe?

I hope Connie will chime in on this. I had heard that beep pulp was to be avoided, but I haven't really been able to find anything verifiable as to why it should be avoided.
