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.

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.
