Why Large-Breed Puppy Formulas Are Different

  • Share

If you’ve got a big love for big dogs, IAMS™ has a large-breed puppy formula specially made for their nutritional needs.

 

 

Nutritional Objectives

Many large-breed puppies have a tendency to grow very quickly. Unfortunately, if this tendency is encouraged by overfeeding, developmental bone problems can occur. To avoid these problems, careful feeding management is necessary. This should include

  • Consideration of optimal protein quantity and quality
  • Restriction of the energy-containing fat
  • Careful control of the calcium and phosphorus levels

 

Our specially formulated large-breed puppy formulas make feeding management easier because they are designed for fast-growing, large-breed puppies (those with an expected adult weight of more than 50 pounds).

 

 

Protein in Puppy Food

A protein level approximating 26% in these formulas promotes healthy body condition and balances the protein with the reduced number of calories in the food. Research has shown that

  • Dietary protein levels from 15 to 32% have no adverse effect on skeletal development.1
  • Body condition decreases as protein gets too low.

 

The protein in our large-breed puppy formulas supports normal skeletal and muscular growth.

 

 

Calories and Fat in Puppy Food

Fat contributes more than twice as many calories in a diet as proteins or carbohydrates do. As the fat level increases, the energy content of the diet also increases, making feeding management more difficult for large-breed puppies. Several studies have shown increases in developmental bone problems when a diet was overfed.2, 3
 

By reducing the fat content of large-breed puppy formulas to about 14%, the metabolizable energy (ME) of the diets can be kept to a low level of about 1,800 kilocalories per pound.

 

 

Calcium and Phosphorus in Puppy Food

Fat contributes more than twice as many calories in a diet as proteins or carbohydrates

 

 

Comparing with Our Other Puppy Foods

Our large-breed puppy formulas, such as IAMS ProActive Health™ Smart Puppy Large Breed, are made specifically for growing puppies with expected adult weights of 50 pounds or more. These puppy foods are unique because they are formulated with:

  • Less fat for fewer calories to optimally reduce growth rate of large-breed puppies and help safeguard against overconsumption of energy
  • A lower level of protein to ensure a proper balance of protein with energy content

 

Reduced calcium and phosphorus levels with a normal calcium-to-phosphorus ratio to promote proper bone development in rapidly growing large breed puppies.

    Puppy Basics: Nutrition for Small and Toy Breeds

    • Share

    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.

     

     

    What Food Should You Feed Your Small-breed Puppy?

    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:
     

    • Vitamin-rich fish oils to support overall health
    • Essential vitamins and minerals to help support the immune system and help your puppy stay healthy during this critical stage of growth
    • Animal-based protein sources to help nourish growing muscles, vital organs and your puppy’s skin and coat
    • A fiber source that will help keep your puppy’s sensitive digestive system healthy, so more nutrition stays in your puppy
    • Ideal levels of calcium and phosphorus to help your puppy develop strong teeth and bones
       

    These are important building blocks of nutrition. Look for them when you choose dry or canned dog food and when you select treats.

     

     

    Why Do Small-breed Puppies Need Specialized Nutrition?

    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.

     

     

    How Much and How Often Should You Feed Your Small-breed Puppy?

    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!

     

     

    When Should You Switch Your Puppy to Adult Food?

    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.
