It is true that the ancestors of dogs (wolves, jackals and wild dogs) are mostly carnivorous, but domestic dogs that we have today are very different from their ancestors.
Dogs do still need a largely meat based diet, however their digestive systems have changed over time (due to the types of food they have been fed over the generations of domestication, quite often table scraps, or 'human' food) to be able to digest and use nutrients from other sources (such as vegetables and grains) so they could be considered Omnivorous like humans. This is convenient for us as giving a dog (especially a larger breed) a diet consisting solely of meat and animal parts would be expensive, messy and time consuming.
You can feed your dog a grain free diet, however it will still contain a filler of some kind (most commonly potato/sweet potato) which is still not meat.
Also you will still need to feed your dog some kind of vegetable to ensure they get the proper balance of nutrition (wolves and such get the extra 'plant matter' by eating the contents of their prey's stomach. Even BARF (which many people feed because of the argument that ‘dogs are carnivores) is not a fully meat diet, usually containing a mix of vegetables and berries to provide a fully balanced diet.
Finally you need to consider the difference in lifestyle of our house pet dogs and their carnivorous ancestors. Generally a house dog will have a couple of short/medium walks a day and spend most of their time lounging, playing or sleeping whereas a wolves etc. will spend most of the day roaming and hunting for food, often having to defend their territory and travel multiple miles a day. Our house dogs get fed routinely at least once or twice a day whereas wild dogs will often ‘fast’ for as long as 2 weeks after binging on fresh raw meat in order to allow their digestive system to fully digest and recover from the meal. Therefore the protein and energy needs of our house dogs are far less than their wild cousins.
Of course, if you own a team of sled dogs and live in an area where it is easy for you to kill fresh, clean meat for them, I would strongly encourage you to feed a high protein kibble and supplement with raw meat due to their active and demanding lifestyle. However if you own a Chihuahua or Shih-Tzu that will spend most of his day sitting by your side, or trotting around the house with you at a slow and steady pace can you really say that this dog will need or even be capable of fully using a high protein diet?
Yes it is not natural for dogs to eat grains, however it is also not natural for humans to drink cow’s milk or use dairy products, (which is why many people are lactose intolerant to some degree) but we have grown to rely on them quite heavily as a source of calcium.
I do agree that a grain free diet could quite possibly be better for a lot of dogs than one with (even high quality) grains... however for most people it is financially not possible whereas finding a good quality food that contains some high quality grains is possible, and can still allow a dog to lead a long and very healthy life.
@CyaNide27- The website given by michael9413 (post #will give you a decent review, it is quite a famous and very useful, easy to understand site. Also if you look through the reviews of other foods given in this thread you should be able to determine if it is a good food or not for yourself. Perhaps you could try putting your own analysis of the food for other people to see. If you have any difficulties with certain ingredients try looking them up on Wikipedia, if you are still stuck you can post up and others can help with the analysis.
Also expensive brands are not always good (but cheap brands, unless very new are pretty much always bad). Always always look at the ingredients and nutritional content no matter what price the food is.
