Dogs are as unique as people, but despite their differences, they all need a well-balanced diet for good health. However, dogs of different ages and sizes have different nutritional needs, and this is especially true for puppies. When you factor in developmental needs, ingredients and your puppy’s size and breed, choosing the right food can be difficult.
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. Feed your puppy this formula based on the recommended amounts for his weight and age until he is an adult.
Although large-breed dogs have bigger bones than medium or small breeds, large-breed puppies do not need more calcium. University studies have shown that:
Overfeeding and weight gain can contribute to developmental bone problems. This makes managing food intake even more critical. Puppies are at greater risk for developmental bone problems if they are overfed.
A formula with reduced fat and calories promotes optimum growth. Controlling the rate of growth to promote normal development is another reason to feed a large-breed diet, such as IAMS™ ProActive Health™ Smart Puppy Large Breed.
Medium-breed puppies have needs between those of large- and small-breed dogs. A medium-breed puppy’s nutritional demands can be satisfied by feeding a 100% complete and balanced formula that features moderate amounts of all the essential vitamins and nutrients, such as IAMS ProActive Health Smart Puppy Original.

Small-breed puppies have unique needs due to their small mouths and small stomachs, as well as the rapid growth spurt they experience when growing to adult size. That’s why it’s important to pack a lot of nutrition and energy into a small amount of food. A poor-quality diet might fill a puppy’s stomach before he can eat enough food to satisfy his nutritional needs. The result can be improper muscle and skeletal development and growth impairment.
IAMS™ puppy foods are formulated to be energy- and nutrient-dense to meet the needs of growing puppies. The IAMS™ formula for small and toy puppy breeds, IAMS™ ProActive Health™ Smart Puppy Small & Toy Breed, has concentrated nutrition for the lifelong health of your small- or toy-breed dog.
Good nutrition is as important to your dog’s health as it is to your own. But with thousands of different pet foods available, how do you pick the right one for your dog?
Learn how to choose a dog food that provides the proper, balanced nutrition your dog needs to thrive with these six tips.
In general, while a human diet should be high in fiber and low in fat, a dog needs more fat for energy and a healthy skin and coat, and less fiber for good intestinal health.
Preferably, a dog’s food should include meat, too. Even if you prefer a vegetarian diet, designing a high-quality dog diet without animal protein is difficult. IAMS™ Company research supports that meatless meals might not provide optimal nutrition for dogs. Dogs are best fed as carnivores because they have simple stomachs and short intestines that are ideal for digesting animal protein and animal fat. Dogs also need carbohydrates for energy.
Start by identifying your dog’s life stage and lifestyle. Puppies, nursing mothers and mature pets each represent different life stages, and each one has different nutritional requirements. By law, all dog foods must state the life stage for which they are recommended.
Nutritional needs also vary depending on lifestyle. A dog whose primary activity is guarding the couch doesn’t need as much energy as one who guards a flock of sheep. Another factor to consider is breed size: small, medium or large.
Finally, consider medical conditions your dog has, such as food allergies, that might require your veterinarian to recommend a special diet.
Once you’ve determined your dog’s life stage and lifestyle needs, decide whether to feed him dry or canned food. Most dogs do well eating only dry food. Dry foods promote oral hygiene for healthy teeth and gums through abrasive chewing action. Some dogs, especially finicky eaters, enjoy wet food because of its smooth, wet texture.
Remember that while dry food can be left in a bowl all day, wet food should be thrown away after 30 minutes if not consumed. Dry food is the best choice for busy people who are not normally home during the day.
After you determine your pet’s nutritional needs and preference, you are ready to go shopping.
Ingredients on dog-food labels are listed in descending order according to weight. Because dogs thrive on animal-based diets, it’s best to pick a food that features an animal-based protein source, such as chicken, lamb, fish or egg, as the first ingredient. Unlike a single-vegetable-based protein source, such as soybean meal or corn-gluten meal, animal-based protein sources contain adequate amounts of essential amino acids.
Scientific studies show that a combination of carbohydrates in the diet, such as corn meal or barley and grain sorghum, offers optimal carbohydrate digestibility and helps maintain energy levels. In addition, scientific studies show that beet pulp — the material remaining after sugar is extracted from sugar beets — is an excellent fiber source and promotes a healthy digestive tract. Finally, for a glossy coat and healthy skin, your pet needs fat in the diet. Good fat sources include chicken fat and fish oil.
Dog-food labels provide limited information about the nutritional value of the food because labeling regulations do not allow manufacturers to describe the quality of ingredients on the package.
A reputable pet-food manufacturer will be able to explain their specific methods for evaluating and assuring the quality of ingredients used in its products.
When choosing food, the price on the bag, while important, is usually not the best consideration. A low price might indicate inexpensive ingredients, or ingredients that change as market prices fluctuate.
Also, many lower-priced products have higher daily portions to provide the same amount of nutrition found in a high-quality diet. To get a better representation of value, it is the cost per feeding, not the total cost, that counts.
To figure cost per feeding, divide the total cost by the number of days the product lasts. For example, a 20-pound bag of food costs $18.99 and lasts 30 days. The cost to feed is $0.63 per day. A 20-pound bag of food that costs $15.99 and lasts 20 days costs $0.80 per day. So, when costs are analyzed properly, high-quality pet foods compare quite favorably to other brands while offering outstanding nutrition.
