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.
Not all small dogs have the same nutritional needs. Giving your dog a food specially formulated for her size and activity level is the easiest way to make sure you’re providing complete and balanced nutrition. Here’s how to provide the right nutrition for your small dog.
Small adult dogs require a food that offers complete nutrients essential for health and vitality. Here’s what to look for:
These ingredients are the keys to nutrition whether you feed dry or wet dog food or give your dog treats.
Small dogs have small mouths and stomachs. You may want to feed your dog a formula with a small bite size for easy chewing. A nutrient-dense food will help make sure she’s absorbing essential nutrients even though her stomach can only accommodate what seems like a small volume of food.
When choosing a food for your small-breed dog, also ask:
Special conditions like these dramatically affect your dog’s nutritional demands.
Less-active dogs and dogs who have been neutered or spayed are prone to weight gain. Controlling your dog’s weight is an important step toward protecting against complications of excess weight, such as diabetes or joint health problems. If you use a weight-control food, look for these ingredients:
Starting in the seventh week of her pregnancy, a mother dog will need to increase her energy intake up to 50% by the time she gives birth and increase it even more when she starts nursing her puppies. Because she may lose her appetite at times, it’s important that she eats a nutrient-dense food. A complete, balanced small-breed puppy formula can give her the extra nutrients she needs.
Unlike larger dogs that are considered mature at age 5, your small dog can remain on an adult diet until age 7. In fact, small-breed dogs tend to live longer and don’t experience age-related changes as early as bigger dogs. However, it is important to make a proactive transition to a specially formulated mature diet, such as IAMS™ ProActive Health™ Mature Adult Small & Toy Breed, so you can help keep your dog healthy and active for years to come.
