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.

As a veterinarian, I’ve found that pet owners take seriously the responsibility of ensuring their dogs live healthy, happy lives. They worry about making sure their dog gets enough exercise, receives regular wellness checks and receives balanced nutrition that gives them energy to run and play.
What some people don’t realize is that owning and caring a dog can improve the owner’s health as well. Spending quality time with your dog and providing them with quality nutrition is good for the dog and can help ease stress and anxiety levels for you. Studies have shown that owning a pet can decrease blood pressure, cholesterol levels and triglyceride levels — which is great news for your heart health.
In short, when your dog is getting the best care, proper exercise, nutrition and love, they can enjoy a long and healthy life. And that can ultimately make you healthier, too!
Many owners see their dog as part of the family, and that sometimes means they will feed their dog like they feed themselves. For example, some people may choose low-carb or gluten-free diets for themselves and do the same for their pets. However, while this instinct comes from a place of love, many owners don’t realize that their dog’s dietary needs differ from their own.
Take grains for example. As a veterinarian, it’s important for me to note that grains are good for your dog. Yes, you read that right — they’re good!
A very small percentage of dogs may have a food sensitivity that requires a special grain-free diet or a dog food without a certain protein. However, this is not necessary for the vast majority of dogs. Most dogs benefit from a complete, balanced diet with healthy grains, high-quality proteins and essential vitamins and minerals.
Here’s why: Grains are a good source of carbohydrates that provide healthy energy. Some grains, like rice and wheat, provide “quick” energy, while other grains, like barley and sorghum, take longer to convert to energy. A combination of these different grains can offer a time-released energy source that helps dogs sustain energy. The whole grains in IAMS dog food are a beneficial mix, as they supply steady energy.
In addition to the grains you’ll find in IAMS food, you’ll also find high-quality proteins, like chicken and lamb, as well as essential nutrients needed to help support heart health. Together, this combination will give your dog a steady source of energy to be active on walks, runs, hikes or play sessions around the house.
For your dog to be healthy and happy, be sure you feed them a well-balanced diet and allow them enough exercise time. In return, you’ll get unconditional love, plenty of sweet doggy snuggles and maybe even more exercise — just a few of the ways you and your dog are joined at the heart.
