I found this article to be very interesting in general and challenged at least one piece of received wisdom:

ie that all kibble was slower to digest than meat/fat in a dog's gut.

It seems there is a slight consensus that highest performance kibble now do a better job than either raw or cooked meat of keeping weight on hard working sled dogs.

Has anyone used Eagle Ultra or Caribou Creek food with other types of working or pet dogs?

As an aside, this article was interesting to me as a (fading) adventure racer who has done non-stop multi-day events, in that for humans it is necessary to feed much more frequently than dogs when exercising at a medium to high level of output: ie every thirty minutes to an hour load up on a mix of carbs and some fats, or bonk big time...

I also note that the human body gets into all sorts of intestinal difficulty during extended (ie more than 24 hour) exercise, as do sled dogs to a lesser extent. It seems that the kibble diet for sled dogs probably is less challenging bacteria wise than either raw, or poorly preserved cooked meat.

hope you enjoy this nutritious fodder for discussion!

Andrew, Certainly food for thought. <img src="http://www.leerburg.com/ubbthreads/images/graemlins/grin.gif" alt="" /> I find it interesting that each of the mushers does something a little bit different. Jest of the article is what works best for them and their team. Feeding is "an art not a science". My thoughts exactly. Thanks for the link.
