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.

Many factors influence the overall health of your dog’s skin and coat: His diet and grooming schedule, the presence of parasites and seasonal changes can all play a role. Whether your dog is prone to skin issues or you want to ensure your pup’s health for years to come, you’ll need to keep a few key things in mind.
Regular veterinary checkups will ensure that your dog is disease- and parasite-free. Flea-bite allergy and external parasites, such as mange, are primary causes of hair loss and skin problems.
In addition to scheduling checkups, check your dog’s hair and skin at least once a week for signs of fleas (flea dirt or bites), mange or other skin conditions, and hair loss.
If your dog’s skin seems thick or scaly or lacks elasticity, or if you notice hair loss, these signs might indicate a nutritional deficiency. Check with your veterinarian, and try feeding him a premium food. It will usually take between six and eight weeks after a diet change to see results. If your pet continues to scratch and chew his skin, consult a veterinarian.
When looking for a dog food that will promote good skin and coat health, keep the following in mind:
What's the best thing you can do for your dog’s skin and coat health? Feed a high-quality food packed with protein, such as IAMS™ ProActive Health™ Adult MiniChunks. Dogs are best fed as carnivores: They need protein and thrive on diets rich in animal-based protein sources. Additionally, their hair is actually 95% protein! Although coat growth varies by breed, the combined growth of all the hair can add up to 100 feet per day in some dogs. This means that nearly 30% of the animal’s daily protein requirement is used just for coat growth during some seasons.
Premium pet foods are carefully formulated to be complete and balanced, which means the food includes all of the nutrients your pet needs. Ingredients in premium foods are highly digestible so your dog's body uses the nutrients efficiently. Less costly foods might contain lower-quality proteins. Though a bag of premium food may cost a bit more than other brands, you might be able to feed less, which minimizes the cost difference.
It’s easy to spot a healthy-looking dog: He has a gleam in his eye, a bounce in his step and a glossy, healthy coat. That glow is a reflection of your dog’s overall health and a good gauge of what’s going on inside and outside.
Regular grooming helps take care of the “outside” by removing loose hair, dirt and mats, and distributing skin oils. Grooming lets you check your pet closely, catching any skin problems early. Plus, your dog will love the attention!
As dogs age, their skin might become more sensitive. Select a mild dog shampoo for your older dog. Shampoos made from coconut or palm oils are the mildest. Unusual or “doggy” odors can signal disease, so if odors persist, contact your veterinarian. Do not use human shampoos because they are often too harsh for a dog’s skin.
When bathing your dog, be sure to rinse him thoroughly. Residue left on the skin can be irritating. You might want to follow the shampoo with a hair conditioner to control static electricity and add extra body or sheen.
During the summer, pay close attention to your dog’s skin and coat. Many dogs shed a winter coat and others face flea problems, so it’s a good time to evaluate your dog’s skin and coat condition to nip any problems in the bud.
Attention to your dog's coat and skin from the inside out will produce a healthy, lively dog that is a joy to look at — and a pleasure to live with — every day!
