All living organisms need a wide variety of nutrients — substances from food that provide energy and enable our bodies to function — to survive. There are six major classes of nutrients for dogs and people: water, protein, fat, carbohydrates, vitamins and minerals. Let’s take a closer look at dog nutrition and six essential nutrients your dog needs to eat:
- What it is:A tasteless, colorless, odorless chemical made up of two hydrogen molecules and one oxygen molecule — hence the name H2O.
- Why it’s important:Without water, life cannot exist. Water makes up 70 to 80 percent of a mature dog’s lean body mass. Water’s many important functions include: dissolving and transporting nutrients to the cells; helping regulate body temperature; hydrolyzing protein, fat and carbohydrates for digestion; cushioning the organs and nervous system; flushing waste from the body.
- Special considerations:A dog’s water requirements vary based on health, activity level and environmental temperature. Most dogs self-regulate their water intake to meet their needs. Dogs fed high-moisture foods typically drink less than kibble-fed dogs. All dogs should always have access to clean, fresh H2O.
- Get it from:Straight from the tap fitted with a good quality filter.
- What it is:Along with fats and carbohydrates, protein is a macronutrient, meaning that it supplies energy. Protein is made up of amino acids, the building blocks of life.
- Why it’s important:Protein supplies essential and non-essential amino acids that are critical to life. Proteins give the body structure (think strong hair, skin, nails, muscles and bones) and are necessary to make hormones, neurotransmitters, enzymes and antibodies that keep the body functioning optimally. Dogs must receive the essential amino acids from diet, as their bodies cannot produce them at the required levels. Protein can also supply energy in the absence of sufficient carbohydrates and fats. Because the body can’t store protein, it needs a constant dietary supply.
- Special considerations:Growing puppies and pregnant and lactating females require about twice as much protein as an adult dog at maintenance.
- Get it from:Animal sources such as lean-muscle meats, fish and eggs; plant-based sources such as beans and lentils.
What it is: A macronutrient made up of fatty acids. Dietary fats are either saturated (e.g., butter, cheese meat), polyunsaturated (e.g., fish oil, flaxseed oil, sunflower oil) or monounsaturated (e.g., olive oil).
- Why it’s important:Fat supplies the most concentrated source of energy, with more than twice as many calories as protein and carbohydrates. It also provides essential omega-3 and omega-6 fatty acids; enables absorption of fat-soluble vitamins; protects the internal organs; regulates body temperature; and promotes a healthy nervous system.
- Special considerations:Too much fat can trigger pancreatitis or gastrointestinal issues. Avoid fatty table scraps. Be aware that coconut oil does not supply essential fatty acids.
- Get it from:Low-mercury fish and fish oil; plant-based oils, such as flaxseed and hempseed.
- What they are:Vitamins are organic compounds (meaning that they contain carbon) that are required in small quantities for proper metabolic function. Vitamins can be soluble in fat (A, D, E and K) or in water (B and C). Fat-soluble vitamins are stored in fatty tissues and the liver; water-soluble vitamins are not stored. Because the body can’t synthesize vitamins in sufficient quantities, they must come from the diet.
- Why they’re important:Vitamins play a variety of critical roles, including: regulating calcium and phosphorus levels (D); boosting the immune system (A); serving as antioxidants (C and E); enabling the blood to clot (K); and maintaining nervous system function (B12).
- Special considerations:All home-prepared diets require vitamin supplementation. If you feed a commercial “complete and balanced” food, do not add additional fat-soluble vitamins, as toxicity can occur. Toxicity of water-soluble vitamins is unlikely, as excess is excreted in the urine.
- Get THEM from:A varied diet containing organ and muscle meats and dog-friendly plant-based foods.
- What they are:Minerals are inorganic compounds that the body needs to maintain proper metabolic functions. The body cannot manufacture minerals and so must get them from food. There are two classes of minerals: macrominerals (calcium, magnesium, phosphorus, sodium, potassium, chloride) and microminerals (iron, copper, zinc, manganese, selenium, iodine). Macrominerals are required by the body in higher levels than microminerals, but both types are equally important.
- Why they’re important:Like vitamins, minerals perform a variety of functions in the body that are essential for supporting life, including: constituting a major part of bones (calcium, phosphorus); carrying oxygen throughout the body (iron); assisting in wound healing (zinc); providing antioxidant support (selenium); aiding in nerve transmission (sodium, potassium, calcium, magnesium); and regulating fluid balance (sodium, chloride, potassium).
- Special considerations:Growing puppies require more than double the calcium of adult dogs at maintenance. Calcium and phosphorus levels and ratios must be monitored closely in large-breed puppies to avoid risk of developmental orthopedic disease.

- Get THEM from:Different foods are rich in different minerals. Meat is high in phosphorus, while bone is high in calcium. Organ meats provide copper and iron, while shellfish is rich in zinc.
- What they are:A macronutrient made up of units of sugars, starches or indigestible fiber. Since dogs can synthesize glucose from sufficient dietary protein and fat, carbohydrates are the only nutrient class that is not essential for dogs. Why they’re important: Carbohydrates are the main source of glucose, the “fuel” the body runs on. Although carbohydrates are not an essential nutrient for dogs, healthy carbohydrates supply important vitamins, minerals, antioxidants and plant-based nutrients that help promote optimum health.
- Special considerations:Consuming a portion of energy from healthy carbohydrates spares protein for other important functions. Steer clear of high-glycemic “junk” carbohydrates that provide little to no nutrition and rapidly raise blood sugar levels.
- Get THEM from:Dog-friendly vegetables, fruits, legumes and gluten-free grains.
The fewer of these nutrients that come from food, the more supplementation is needed to fill the gaps.
Check out this list to get you started:
- Water Filtered tap water: Clean; pure; cost-efficient; readily available
- Protein Whole egg: Considered the most bioavailable source of protein (1 large egg provides about 6 grams of protein)
- Fat Sardines: Low mercury; nutrient-rich; high in the essential omega-3 acids EPA and DHA
- Carbohydrates Butternut squash: High in vitamins A and C; loaded with antioxidant-rich carotenes; excellent source of many vitamins and minerals, such as vitamins E and B6, magnesium, manganese and potassium.
- Vitamins Dark leafy greens: Rich in vitamins A, C, E, K and folate; also high in carotenoids and many minerals; shown to
protect against cancer
- Minerals Oysters: Excellent source of copper, iron, magnesium, manganese, phosphorus, selenium, zinc; also rich in vitamin D and omega-3 fatty acids
Dog Food and how to select the best one for your pet
There are a variety of pet foods available in the market but not all are the best for your pet. The quality of the food depends upon the quality of the raw materials used as ingredients in the food, the process of manufacturing and the formulation. It is also a myth that a costly food is best. Also, pet parents must also take care about the source or the place of purchase ie how is the storage facility, the handling of the goods and the flow of the stock altogether.
The best food can be selected keeping in mind the health status of the pet, the physiological needs of the pet depending on age, pregnancy, lactation, level of exercise etc. So your vet will be the best person to guide you of your pet’s best nutrition. Get in touch with us for further details.
