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.
Low-cost food might be better for your wallet, but it can be a raw deal for your dog, because he may not get the nutrition he needs. Premium foods, such as IAMS™ ProActive Health™ Smart Puppy Original , make sense both nutritionally (because of consistent, high-quality ingredients) and economically because they provide:
The investment in a premium food might initially cost more per bag, but because these high-quality formulas are high in nutrient density, your dog may need less food, which can offset the higher cost per unit of weight. On a cost-per-feeding basis, look at how much you feed each day as opposed to how much the bag costs, because nutrient and energy density will generally be lower for a low-cost food compared with premium foods.
With budget-priced formulas, the emphasis is on production and ingredient costs. Two bags of the same least-cost formulated food can have different ingredients and/or levels of ingredients. Plus, those ingredients may vary significantly in digestibility. This means, simply, that you may need to feed more just to equal the nutrition offered by a smaller amount of a premium dog food formula.
High-quality, complete, and balanced premium dog foods such as the IAMS brands are specifically designed to provide your dog with a food that has:
To determine how much food to give your dog, check the daily feeding recommendations set by the pet food manufacturer and read the label. To calculate portion sizes, divide the total daily recommended amount by the number of times (usually two for adult dogs) you plan to feed your dog.
To tell if your dog is at a healthy weight, move your hands along his sides. If you can feel his ribs, he's about right. Or, look down at him when you're directly above him. You should be able to see a waistline.
If he's gaining or losing a lot of weight, slightly decrease or increase his daily intake and weigh him in another week. If you have specific concerns about your dog's weight, talk to your veterinarian. He or she can assess your dog's needs and make a feeding recommendation.
Once you've decided on a premium formula, you have another choice to make: dry or moist. And what about biscuits?
Premium dry dog food gives you the best value and convenience, while fortifying your dog with high-quality nutrition. Premium dry foods come in a number of bag sizes and formulas suited to size, life stage, and activity level. Dry food also helps keep teeth clean, and it stays fresh for a long time if you store it properly.
Wet foods from IAMS provide 100% complete nutrition. IAMS ProActive Health Puppy Biscuits make great treats and rewards and can add taste variety to your new dog's diet.
