Wow! Thanks everyone for all the links and information!!
I'm not comfortable with a 100% meat diet. I know that coyotes and wolves eat quite a bit of "vegetarian" foods as well. I'm not really sure what they are eating, but simply by looking at coyote and wolf poop you can see that there is definately A LOT of non-meat foods in there. I would like to achieve as close to a "wild" diet as I can, as I'd like to believe this would be the best, but I would be very interested to know if domestic dogs' digestive systems have evolved differently than their wild counterparts...?
Now...to go read those links.
