1. According to the physiological characteristics of dogs: puppies, adult dogs, elderly dogs, pregnant dogs and lactating dogs

2. Divide according to the function of the food eaten: energy part (protein and vitamins, such as beans, fish and other meats, natural protein powder and vitamins, etc.) caloric part (fruits, vegetables, rice, pasta, etc.) We need to according to the function of the pet Match the energy and heat needs differently in the morning and evening.

3. We should pay attention to the amount of meat we feed. It should not be too much, especially animal offal. Because meat metabolism produces uric acid, and animal offal is a high-purine food, catabolism will also produce high blood uric acid, and uric acid is a component that forms stones. Therefore, the daily diet should be a combination of meat and vegetarian food. Dogs are carnivorous animals and need a supply of meat protein. They should also be given food rich in fiber. Eat less salt. A diet that is too salty will increase the workload on the kidneys.

4. Breakfast and dinner should be balanced. 2/3 of the protein throughout the day should come from the morning diet. The protein in the pet's body is rapidly updated and converted all the time. The "quality" of breakfast protein must be paid attention to. A qualified pet nutritional breakfast should be carefully Follow the requirements of the "two elements of food" (energy part, calorie part) and pay attention to the appropriate combination of "protein nutrition" foods, such as meat, poultry, fish, beans and cereals. Breakfast must have staple ingredients. Breakfast is the meal that is least likely to be converted into fat in the day, so you must consume staple foods (meat or meat-rich foods).

The calories provided by a dog’s breakfast account for 30% of the whole day, which is mainly provided by staple food. Lack of carbohydrate staple foods may lead to malnutrition. Eat some starchy foods. Cereal foods can be quickly decomposed into glucose after being absorbed, correcting the hypoglycemia of dogs after a night's rest. However, cereals are digested quickly, and you will feel hungry after 2-3 hours. Therefore, eat some foods rich in protein and fat, such as meat or foods rich in meat.

Dogs should eat less for dinner so that they can sleep well. The specific amount depends on the breed, size and other physical conditions of each dog and the needs of the dog's own body. It is based on the amount of food we often feed the dog so that he is not hungry. Don't be full at dinner, let alone overeat. Otherwise, some dogs will vomit up after eating.

Secondly, you should choose foods rich in fiber and carbohydrates for dinner. There should be two or more vegetables at dinner to increase vitamins and provide fiber. Milk is also a very good choice. It should be determined according to personal economic conditions. You can eat a small amount of meat. After all, our pet activities at night do not require a lot of energy.
