1. High-quality protein: Dogs need to get enough protein to maintain normal physiological function. They can choose animal meat such as chicken, fish and beef, and plant protein such as beans and cereals.
2. Fresh fruits and vegetables: Dogs need to eat some fresh fruits and vegetables to supplement various vitamins and minerals, such as carrots, spinach, broccoli, apples and blueberries.
3. Whole wheat food: You can choose foods rich in carbohydrates such as cereals and whole wheat bread, which can provide enough energy for dogs.
4. Natural organic food: Try to choose natural organic food, and don't choose refined food that is processed too much. These foods have low nutritional value, and additives and seasonings may affect the health of dogs.
In short, dogs need a balanced diet to maintain a strong body and immunity. If you are not sure, please consult a professional pet nutritionist.
