Your small- or toy-breed puppy grows rapidly in the first months of their life: Their immune system is developing, their bones are growing and their muscles are getting stronger. With all this growth, they need the right mix of nutrients to support their development. To make sure your puppy is getting the proper nutrition to protect and maintain their health and well-being, keep these key points in mind.
Research shows that puppies need up to twice as much energy as adult dogs. Because they are growing so quickly at this stage, your small-but-mighty pup needs an energy-rich, nutrient-dense small-breed dog food like IAMS™ Puppy Small Breed. Puppies also need more protein than adult dogs. High-quality animal-based protein will help your puppy create new body tissue as they grow.
Aside from protein, make sure these other important nutrients and ingredients are a part of your puppy's diet:
These are important building blocks of nutrition. Look for them when you choose dry or canned dog food and when you select treats.
When it comes to feeding puppies, one size does not fit all. Small-breed puppies have higher metabolism rates per pound and reach their mature adult weight faster than larger-breed puppies. And small-breed puppies need high levels of protein, fat, calcium and phosphorus to support the growth and development of their bones, muscles and other tissues. So, giving your puppy a food that supports their breed size is the easiest way to make sure they’re getting the right balance of nutrients for their growth rate.
And remember: Small-breed puppies also have small mouths and stomachs! Make sure your puppy's food has small kibble for easy chewing. A nutrient-dense formula will help your puppy get a complete and balanced diet even though their stomach can only hold what seems like a small amount of food.
From the time your puppy is weaned until 4 months of age, you should feed your puppy two to three times a day. Check the food label guidelines to feed them the proper daily amount. After your puppy is 4 months old, feed them twice a day on a regular schedule. And make sure they always have access to fresh water, too!
A small-breed puppy reaches adult weight faster than larger breeds. You can start feeding an adult dog food, such as IAMS™ Adult Small Breed, when they are around 9 to 12 months old.
Your dog might not be thrilled about the change at first, but don't worry. You can help ease the transition by gradually introducing the adult food. Try mixing 25% of the new food with 75% of their puppy food, and then gradually change the proportions over the next three weeks until they are eating 100% adult food.

Switching your dog to a new food takes some planning. Because dogs are creatures of habit, they tend to prefer their current food to a new food. Like us, they become accustomed to a food and might not be thrilled about a new routine. These useful dog-feeding tips will help you keep your dog satisfied.
When easing your dog into a change in diet, think “slow and steady.” Start by mixing 25% new food with 75% current food. Slowly change the proportions over the next three days or so by gradually increasing the new food and lessening the amount of the current food. Here’s a sample feeding schedule:
At the end of this weaning process, you should be feeding 100% of the new food. Your dog may want to eat only the old food, or not eat at all. Don’t worry — a healthy dog can miss meals for a day or two with no ill effects.
Bringing a new food into your home, pouring it into your dog’s bowl and declaring that he should eat it might cause your dog to go on a hunger strike. This is not the time to show who’s boss. It’s better to introduce the new food by using a pleasant tone of voice and gently encouraging him to try the new food.
Persistence is key! For the first two days of the food transition, don’t give your dog treats or table scraps. Dogs train us as much as we train them. Giving in to their demands only reinforces refusal behavior and makes it more difficult to make a nutritious dietary change.
Switching diets may be more challenging when changing from a moist food to a dry food. If your dog continues to resist eating dry food, mix in a little warm water. You might even want to put the moistened food in the microwave for a few seconds. If you mix the food with water, be sure to throw away the uneaten portion after 20 minutes to prevent spoilage. The same rule applies for canned and pouch food. After the dog has become accustomed to the moistened food, you can wean him onto completely dry food. To do this, follow the same mixing instructions outlined above.
