We learned from canned dog food manufacturers that dogs usually need basic nutrients such as water, protein, fat, carbohydrates, minerals and vitamins.

Among them, proteins are complex molecules composed of amino acids, which are the basis for cell growth and repair. In general, meat, meat by-products, eggs, and dairy have the highest levels of protein that dogs can digest efficiently, providing amino acids in proportions suitable for protein synthesis. Conversely, most plant proteins are of lower utilization value due to deficiencies in specific amino acids and lower digestibility. Fats Fats are the main source of energy, and they also provide fatty acids that are essential for maintaining healthy cells. Fats work with protein to enhance the palatability of foods and aid in the absorption of fat-soluble vitamins A, E, D, and K.

While dogs don't need carbohydrates, carbohydrates that can be digested and broken down into glucose can also be a source of energy. Carbohydrates are also found in vegetables and fruits, which also provide minerals, fiber, antioxidants, phytochemicals, and certain proteins. Vitamins are organic substances that maintain the normal functioning of the body.
