Dogs usually need basic nutrients such as water, protein, fat, carbohydrates, minerals, and vitamins.

Proteins are complex molecules composed of amino acids, which are the basis for cell growth and repair. Generally speaking, meat, meat by-products, eggs, and dairy products are high in protein, and dogs can effectively digest these proteins by providing amino acids in ratios suitable for protein synthesis. On the contrary, due to the deficiency of specific amino acids and lower digestibility, the utilization value of most plant proteins is relatively low. Fats are the main source of energy, and they also provide fatty acids that are crucial for maintaining healthy cells. Fats, together with protein, enhance the palatability of food and help absorb fat soluble vitamins A, E, D, and K.

Although dogs do not require carbohydrates, carbohydrates that can be digested, broken down, and converted into glucose can also be a source of energy. Vegetables and fruits also contain carbohydrates, which can provide minerals, fiber, antioxidants, phytochemicals, and certain proteins. Vitamins are organic substances that maintain the normal functioning of the body.

In the process of raising pets, it is important to cultivate good eating and living habits for them. When choosing food, it is important to consider the suitability of the pet. Canned food is convenient to consume and can also provide the necessary nutrition and hydration for the pet.
