I agree with Zero Cool that these products are a waste of money. The primary ingredient is invariably maltodextrin, a highly-processed starch, used in the production of candy. To that these companies then add powdered (devalued) egg, powdered (devalued) liver, and then a bunch of vitamins ... so why not just save yourself the wasted money and buy whole (full-value) liver, whole (full-value) egg, and not even bother with the maltodextrin?

In the end, there has been no "debunking" of the fact FATS and OILS are the primary source of energy in a working dog. Your dog should get no more than 15% carbs, if even that. At least 50% of your dog's diet should be high-quality fats/oils derived from raw meats. The rest should be proteins and whatever trace elements are found in the veggie mix you provide him. I also recommend a Pedialyte supplement to replace lost electrolytes and minerals in heavy training.

Jack I notice you have vertex and power chow in your keep did you take them out or is it still in your program
