Diet plays an important role in the endurance potential of canine athletes. The Alaskan sled dog might be considered the ultimate canine athlete, sometimes pulling a sled more than 1,000 miles in subzero temperatures. Providing a well-balanced diet is essential to meet the special needs of dogs in such nutritional-stress situations. Not only should the diet fed to these dogs be high in protein, but it also should be high in fat, which serves as the major energy source for exercising muscles.
A high-fat diet can help muscles burn fat more efficiently. During sustained exercise, fatty-acid oxidation is the primary source of energy for the muscles. Increasing the efficiency of fat metabolism spares the body’s use of carbohydrates, and because most dogs have in excess of 10 to 50 times more energy stored in fat than in muscle glycogen (carbohydrate), this might boost the animal's exercise performance.
IAMS™ studies1 have shown that in trained sled dogs as in ordinary dogs, exercise performance was enhanced by switching from a low-fat to a high-fat diet (from 25 to 65% of calories from fat), as indicated by increased:
When dogs were switched back to a low-fat diet, all of these criteria decreased to their previous values.
These results indicated that by increasing the availability of fat stores and capacity to metabolize fat for energy, a high-fat diet promotes exercise endurance in canine athletes.

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.
