The dog’s need for nutrients

Dogs need a variety of nutrients to live: protein, fat, carbohydrates, vitamins and minerals. Their doses depend on the individual characteristics of the dog – its age, size, health and activity level.


Protein is a must in any dog’s diet. The amino acids contained in it serve as a building block for the body and a source of energy. High-quality protein will contain essential essential amino acids for the dog, which the quadruped cannot produce on its own. Animal protein has a higher content of these amino acids and is easier to digest than vegetable protein. Therefore, the dog’s diet should be based on animal products. Protein and individual amino acid deficiencies can cause muscle wasting, various malformations and metabolic diseases.


Fats are the main source of energy for dogs. However, they are a source of not only calories, but also essential fatty acids and fat-soluble vitamins. Omega-3 and -6 fatty acid deficiencies will result in, among other things, an ugly coat and neurological disorders. These ingredients are mainly contained in animal fats.

Dogs need a certain amount of energy (calories) to maintain their vital functions and daily activity. This energy comes from protein, fat and carbohydrates. Carbohydrates are not an essential part of the diet of pets, but they are a source of easily digestible energy.

Growing dogs may need up to twice as many calories as adult dogs of the same breed. However, in older dogs, due to reduced activity and slower metabolism, the energy requirement is reduced by up to 20% compared to adult dogs.

Vitamins are involved in a number of processes necessary for a dog’s body to function. Deficiencies of these ingredients can cause visual disturbances, skin diseases, respiratory problems, neurological disorders or muscle atrophy. Also, an excess of certain vitamins is dangerous to the health of pets.


Minerals are necessary for the proper functioning of organs and the development of the body. Calcium and phosphorus are responsible for the health of bones and teeth. Magnesium, potassium and sodium are involved in muscle work and neurotransmission. Many other minerals are ingredients for the synthesis of enzymes and processes in the pet’s body. Deficiencies and excess of these components will cause serious developmental defects and organ dysfunction.

How to meet your dog’s nutritional requirements?

Dog owners who feed their pet high-quality dry or wet food do not have to worry about deficiencies or excess of nutrients.

However, the dog’s nutritional requirements must be well known by those owners who feed the dog with a diet prepared at home.
