Vets. always push dog food because they make a lot of money from them. They don't know much about nutrition or feeding "real" food since they are not trained.
I've only have one Vet. over the past 50 years that agreed that feeding real food is the safest and healthiest way to go, so don't be too surprised if your Vet. tries to make feeding real food too complicated in order to sell you commercial food.
Since so many people are switching to real food for their dogs and cats, and so many recalls and deaths in animals, more and more Vets. are re-thinking their idea that pet food is best. Thankfully!
It isn't a science feeding real food. So far, there is not one person on the planet that are experts in this field. It's just trial and error. Most of us know what not to feed, so the rest is simple. Keep it simple though.

FRUIT
Dried fruits such as figs, dates, prunes, and apricots as well as fresh fruits like apples and berries.
Like vegetables, fruits are a great storehouse of vitamins, minerals and vital energy. For best digestion, feed such foods apart from the regular mealtime. Dried fruits are especially good natural sources of potassium, an important mineral that can sometimes be in short supply. Dates are extremely rich in folic acid, an important B vitamin.
VITAMINS
HEALTHY POWDER
2 cups nutritional (torula) yeast
1 cup lecithin granules
1/4 cup kelp powder
1/4 cup bonemeal (or 9,000 milligrams calcium or 5 teaspoons eggshell powder)
1,000 milligrams vitamin C (ground) or 1/4 teaspoon sodium ascorbate (optional)
Mix all ingredients together in a 1-quart container and refrigerate.
Add 1 to 2 teaspoons per day for cats or small dogs; 2 to 3 teaspoons per day for medium-size dogs; 1 to 2 tablespoons per day for large dogs.
VEGETABLE OIL
Vegetable oils are all excellent sources of linoleic acid and other important unsaturated fatty acids needed by both dogs and cats.
