Oh dear I have really started something here! Maybe if some of you were to do some research yourselves, you would have a better idea rather than just getting angry about things that you may or may not have knowledge or experience of.
Just a quick google search came up with the following information found on the Hill's website (dog nutrition experts).
'Omnivores, such as dogs and people, don't have higher requirements for taurine and certain vitamins and can create their own arachidonic acid from vegetable oils.
Omnivore qualities
There are other nutritional, behavioral and physical factors that separate the omnivore and carnivore worlds:
Dogs have teeth (molars) with relatively flat surfaces designed to grind up bones as well as fibrous plant material.
Dogs can digest almost 100% of the carbohydrates they consume.
Dogs have a small intestine that occupies about 23 percent of the total gastrointestinal volume, which is consistent with other omnivores; the small intestine of cats occupies only 15 percent.
Dogs can create vitamin A from betacarotene found in plants.
Confusion in their conclusion
Some folks have come to the erroneous conclusion that dogs must be carnivores because they fall under the order Carnivora. A close look at the anatomy, behavior and feeding preferences of dogs shows that they are actually omnivorous — able to eat and remain healthy with both animal and plant foodstuffs.'
If any of the haters can find some studies or information that shows otherwise, I would be happy to read it.
Again, as I previously mentioned, I would also look into a raw meat diet, so I am not forcing my views on my dogs and there is no need for anyone to be concerned. I would be more concerned with the crap that goes into commercially produced dog food. All the antibiotics and hormones that factory farmed animals are fed cannot be good for anyone. I am doing careful research into a diet that would best suit my dogs and this is one area I am looking at.
