The Freegan dog...

So here is the thing: dogs and humans are ommivores. Dogs' roots are predominantly carnivore and humans' are predominantly vegetarian. There is not really much debate on any of this, you can look at our pathetic canines, muscles, speed etc when compared to real carnivores or even omnivores like bears, wild boars etc. You can also look at the length of our intestines, the fact that our mandibles are able to move from side to side like most rumiants, sweat glands instead of panting and lots of other minor little details (like for example, have you cut your claws recently?! do you think  you could kill a rabbit with those?!). Longer video cartoon on this point in this funny vegan video.
