The dogs were/were not decended from wolfs or some missing link debate is mind numbing.
Dogs Wolfs & other wild canids digestive system is virtually the same despite thousands of years of domestication. They have very short intestinal tracts geared to the consumption and digestion of raw foods.
The amount of predigested plant material availble does not negate the fact that wild canids do not only eat the gut, they eat it 1st.
It's irresponcible for any Dog Food Guru to suggest that meat & bons is a healthly diet choice. Just as the Vegan claim that mat is unnessary.
Fom my stand point as dog owner and a hunter with personnal observations of wild canids I find it funny when pepoplethat never leave thier living room theorize about the natural world.
