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.
Teeth are important players in the digestive process.
As teeth grind up food, debris accumulates on the tooth surface and attracts bacteria. This accumulation of debris and bacteria is called plaque. Plaque is easily removed from teeth by brushing—that is, when teeth are brushed frequently.
If the plaque isn't brushed away, mineral deposits cause it to harden on the teeth. This is called tartar. Dark yellow or brown accumulations on the teeth are indicators of tartar, which is difficult to remove.
If left untreated, plaque can lead to damage of the gums (gingivitis) or the jawbones and teeth (periodontitis).
Keeping a pet’s teeth and gums healthy involves regular brushing and professional cleaning. Unfortunately, many owners have problems brushing their dogs’ teeth on a regular basis.
Special diets also can help reduce tartar buildup between cleanings. Most dental diets are formulated with a tough kibble that is texturized to scrape off some plaque.
Our dental technology uses a patent-pending manufacturing process that enables dry-food kibbles to control tartar buildup. This process does not affect the nutrient content of the food or the size of the kibbles.
IAMS™ researchers have looked at the effects of feeding dogs dry diets with our dental technology. In each of these studies, two groups of animals were fed our formula, either with (control) or without our dental technology.
All animals had their teeth thoroughly cleaned.
After 28 days of eating one diet, animals’ teeth were examined for tartar.
All animals then received another thorough cleaning.
Then diets were switched for another feeding period.
In dogs, the diets featuring our dental technology reduced tartar accumulation as much as 50% compared to dogs fed the control diet.'
