The food is otherwise made up of grain for the dog's health.
I think your friend was mistaken. A dog digestive system is very similar to a wolf digestive system, which of course is where dogs come from. Wolves do not eat grains. Their diet is almost exclusively meat, although they do sometimes enjoy a vegetable, and if they get really hungry they will sometimes eat nuts or berries. Dogs and wolves both eat grass sometimes, but that's mostly for the fiber, and they stick to the top of the grass blades which is the most nutritious and hydrated, but it's not much for them. Their systems don't deal well with grains, they don't process them like we humans do. Dogs are not omnivores, they are carnivores. Corn and wheat would never be found in a wolf or feral dog diet, unless the animal were starving to death, even then many probably would not eat it.
Corn is especially bad for a dog, it's broken down into several chemicals in a dog's body that block serotonin. On top of that, the corn does not having any l-tryptophan, which is what is used to make serotonin in we mammals. Want to deplete your brain of serotonin? Eat only corn based products for a few weeks. This is why it's bad for your dog, he or she eats the same stuff day after day. If it's mostly corn, this can have all kinds of adverse behavioral effects on your pup. Wheat is a significant allergen to many dogs, sometimes it manifests in ways that are not obvious to the owner. Dogs can't say "Hey, my joins feel inflamed ever since you started me on that new food. And I have this strange full feeling all the time. You better check my intestines for inflammation."
I am afraid you are very mistaken and you sound very much like a dog food salesman. Dogs have evolved from Wolves over the last 14,000 years and living with us and getting our scraps has changed their digestive system and has changed them. One of my Petey's favorite meals is oatmeal, blueberries, natural peanut nutter, with a hard boiled egg.
Another thing there is only two kibbles that my Pit-mix will eat and will rather go hungry than eat other brands. That is ol roy and puppy chow.
What your dog chooses to eat or not is not indicative of what is good for him/her. Neither is your claim about 14,000 year of supposed evolution. (Evolutionary changes to a digestive system would take longer than that). Dogs CAN and DO eat grains and other non-essential fillers and such in dog foods. Especially lower quality ones. Some dogs will even seem to prosper on it. But ideally, and shown in authoritative research, canines need and survive with a healthier diet based less on grains, fillers, and by-products. But of course, with a little knowledge and research a person could feed their dog foods similar to what you've expressed (with many other foods included) and the pet would likely do well.
I have had dogs my entire life (means nothing really) and in that time I have found that a very healthy diet based on natural ingredients more commonly found in the wild, truly has a positive effect on my dogs. I am not a dog food salesman either.
I find that your opinion is the height of hubris especially on the continual insistence that dogs are wolves and using the word natural and dog in the same sentence is quite entertaining. The fact is dogs are human creations breed and selected for traits that our ancestors found desirable and that process is still happening today. Dogs are not natural and their sole purpose for existence is to serve us and because of this process their diet and needs have changed.
But you can continue to believe dogs are wolves. Also a lot of evolutionary changes can happen in a few generations especially when it comes to survival so over 14,000 years you should expect a lot to change also IMO.
