Nutrients are divided into subcategories: protein, carbohydrates, fats, vitamins and minerals, and water.
Common dog-food protein sources include meat, poultry, fish, and some plant ingredients such as corn gluten and soybean meal.
Protein is best known for supplying amino acids, or protein subunits, to build hair, skin, nails, muscles, tendons, ligaments, and cartilage. It also plays a main role in hormone production.
Dogs, best fed as carnivores, require essential amino acids, that are not all found in the correct balance in single plant-protein sources such as soybean meal.
Common carbohydrate sources are plants and grains. Carbohydrates, also categorized as starches (sugars) and fibers, provide energy and bulk, respectively.
Starches are made up of various types of sugar, such as glucose or fructose. Through digestion, dogs can easily convert sugar into usable energy.
Fiber may or may not be fermented or broken down into short-chain fatty acids by bacteria in a dog's intestines. Highly fermentable fiber sources, such as vegetable gums, provide high amounts of short-chain fatty acids. Moderately fermentable fibers, such as beet pulp, provide short-chain fatty acids and bulk for moving waste. Slightly fermentable fibers, such as cellulose, provide mainly bulk for moving waste through the digestive tract and only a few short-chain fatty acids.
Fats are found in meats, poultry, fish, and plant oils, such as flax and vegetable oils. Fat, for all of its bad press, fulfills many vital body functions. Animal-cell membranes are made of fat. Fat also helps maintain body temperature, control inflammation, and more. Fat is the primary form of stored energy in the body, providing twice as much energy as carbohydrates or proteins.
Fats also provide the important fat subunits, omega-6 and omega-3 fatty acids. Omega-6 fatty acids are essential for skin and coat maintenance and proper membrane structure. Omega-3 fatty acids have been shown to be important in blood clotting and decreasing inflammation.
Vitamins are responsible for promoting bone growth, blood clotting, energy production, and oxidant protection.
Vitamins A, D, E, and K require fat for absorption into the body, while vitamins such as the B-complex vitamins and vitamin C need water to be absorbed into the body.
Minerals provide skeletal support and aid in nerve transmission and muscle contractions.
The energy requirements of a puppy can be nearly twice those of an adult dog. This means that a puppy might not have the stomach capacity to eat enough food to meet his needs unless the food is specially formulated.
When choosing a puppy food, select one that provides a highly digestible, nutrient-dense, 100% complete premium formula for growth. Such high-quality formulas contain the vitamins, minerals, protein, fat and carbohydrates your dog needs for sound and healthy development. With a premium formula, your puppy may have:
Puppies grow fastest during the first six months of life, and because growth rates differ among breed sizes, you need a formula designed to address the needs of your puppy’s breed or size.
No two dogs are alike. So when choosing your pet's food, you'll want to take into consideration the dog's breed, size, age, weight, and lifestyle. Full growth will happen at around 1 to 2 years, with the exact age determined by your dog's breed—small-breed dogs mature faster than large-breed dogs. “Grown dogs, especially ones who are more athletic, will start to eat more quantities in one feeding,” says Madan Khare, DVM. “You want to limit his feeding to one or two times a day, depending on his activity level.” Exact quantities should be determined by consulting your vet or by reading the package labels (just remember to split a daily serving in half if you choose to feed the dog twice a day).
When transitioning your dog from puppy food to premium adult food you want to do it gradually. “Never change a dog's diet abruptly,” Khare says. Here's a schedule for transitioning your pet from puppy food to an adult dog food:
Daily exercise and a diet packed with high-quality protein from chicken, lamb, or fish and essential nutrients will keep him happy and healthy throughout his lifetime. Premium dry pet food has all of the daily nutrition your pet needs. It helps promote healthy teeth and gums, too.
“When it comes to feeding your dog human food, I have three words,” Khare says. “No. No. No.” Interfering with your pet's food regimen by frequent change in diet or nutritionally inadequate human food can disturb the animal's digestive system.
Always remember to pick premium, tailor-made dog food based on the life stage and unique needs of your pet.
