How good is Maidun A6 dog food?

Maidun A6 puppy food has been upgraded to B3 complete puppy food, with main ingredients of chicken meal, flour, fish meal, chicken fat, soybean meal, extruded corn, and rice. The animal ingredients are high-protein, low-fat chicken and fish, but the specific proportion is not stated. The starch sources are flour, corn, and rice, with flour in the second position, so the starch content should be fairly high, and corn is hard to digest and can easily cause allergies. Beef tallow is rich in unsaturated fatty acids, which can make the dog’s coat shinier.
