Here are some great sites with rawfeeding information.  The third is a 
yahoo group for prey model raw, which is what you are asking about.  
Dogs are not built physically to break down and absorb nutrients from 
vegetation.  If you have to puree, process, and mush it all up for them 
to get any nutrition why bother?  Dogs are carnivores, which a lot of 
people don't realize.  They will eat what they can find when food is not 
available, which I think someone mentioned in another thread about 
tubers and humans. : )  When it comes to vegetables, if my dogs choose 
to eat some grass then they are getting vegetation.  Other then that I 
don't give them vegetables, unless it happens to be some leftover I am 
eating that they want to scarf up.
