There's a discussion going on in the nutrition forum and I don't want to hyjack it [

]
Current archeological evidence suggests a few things. First, there was a carnivorous canid that followed its slow-moving prey into extinction. The omnivorous canid became the wolf and other canids, such as the dog. Secondly, what we call dog has been around Man for about 100,000 years, eating whatever we cast off or choose to feed them, cooked, grainy, whatever. Third, Man did not tame the wolf. The more docile and omnivorous canids realized that this man-thing threw off a lot of food that they didn't have to hunt for. By being nice to humans, they got to eat more often. That is, the tamed themselves into symbiosis with Man.
While I appreciate this, my research has concluded a few different things. For one, I assume (I know... shouldn't do that[

]) the first canid carnivore you are refering to is the Dire Wolf, am I correct?
I have also concluded that wolves are true carnivores. My main reason is that I am unable to find and mention of plant matter (in a wolf's diet) anywhere in L. David Mech's book
The Wolf. Rather, statements ( at this time I cannot find it, but I will provide a page number) that state wolve's feed almost exclusivley are larger ungulates and beavers. I am also unable to find a single site on the web that has them listed as omnivores. I am, in all seriousness, interested in reading sources that state they are omnivores. I also wish I could find, somewhere, how much plant matter an animal must consume to be placed in the "omnivore" category (such as 20%plant 80% meat), but I still am unable to discern that as well.
My final question is, how did man
not eventually tame the wolf? Humans, at one point or another, eventually had to tame it... although I, personally am skeptical of the theory that wolves would be around humans scavenging from them, I do think in certain aspects it is plausible. My reasoning is that wolves are extremely shy animals, and after the pups reach a certain age, the seem rather unwilling to experience or accept new things. Also, many groups of people (especially in Europe) would have killed a wolf on site, would they not? Although, when you get to the more wolf-friendly peoples of the Americas, I might believe it more. I find the theory that man took wolf pups and tamed them more plausible, but that's just MHO.
Finally, I might be convinced that some breeds are more omnivorous than others. I think the so-called primitive (or ancient) breeds would require a more meat-based diet. But that is solely my opinion. I am also, still uncertain, as to whether or not
Canis framiliaris
is a subspecies of
Canis lupus or not. I have found conflicting statements on it.
Anyway, I think this is an interesting discussion [

ETA:
Found my passage in Mech's book [

].
On page 14, he states "The wolf feeds almost exclusively on flesh, bones, and other animal matter..."
