Planet Molosser,
I've read your posts about the amazing work you've done with your dogs, so please don't take this the wrong way. I'm simply just pointing something out to the original poster.
Kasco Hi-Energy:
Chicken by product meal, ground corn, poultry fat (preserved with mixed tocopherols, rosemary extract and citric acid), ground wheat, corn gluten meal, beet pulp, rice hulls, fish meal, dried brewers yeast, dicalcium phosphate, calcium carbonate, potassium chloride, sodium chloride, choline chloride, Vitamins [dl-alpha tocopherol acetate (source of vitamin E), biotin, d-calcium pantothenate, niacin, pyridoxine hydrochloride (vitamin B6), vitamin A acetate, vitamin D3 supplement, thiamine mononitrate (vitamin B1), vitamin B12 supplement, riboflavin (vitamin B2), folic acid], Trace Minerals [zinc oxide, ferrous sulfate, copper sulfate, manganous oxide, sodium selenite, calcium iodate].
By-products, corn, wheat, and the unhealthy parts of rice are all things that aren't found in Canidae.
In my opinion, it is worth $10 more for a 40lb bag of Canidae All Life Stages.
